7. Abstract
FOS/RD observations of the core of Eta Carinae at wavelengths 5000--8000 A are
needed to supplement and complete the UV-visual FOS/BL spectra made in 1991. Eta
Car, the very massive, most extreme LBV, has surprising sub-arcsec structure near
its central star.  Spectroscopy of this physically mysterious structure is needed
before we can be sure of the nature of Eta Car, and only the HST/FOS can provide the
necessary spatial resolution. FOS/BL data covering wavelengths 1200--5500 A were
obtained in Cycle 1. Longer wavelengths are needed for many important emission lines
and also to make connection with the speckle images observed around 8000 A.
Moreover, the high FOS/RD count rates for this object will allow far more spatial
information to be obtained than was practical with the FOS/BL detector. We propose
to obtain short-exposure (but high S/N) data on a grid of positions about 1 arcsec
across.  For technical reasons related to the high count rates, Cycle 3 is probably
the last realistic opportunity to obtain these data.

  3. Description of proposed observations.
  With the FOS/RD detector, which we require in order to reach wavelengths beyond
 5500 A, only the smallest FOS aperture (0.1" square) is safe to use on the core
 of Eta Carinae;  Eta is too bright for the other apertures.   Fortunately we do
 not need absolute flux calibrations, so the 0.1" aperture is OK.  This small
 aperture will give the best available combination of spatial and spectral
 resolution, regardless of HST's optical defect. (After COSTAR is installed, the
 core of Eta Car will be too bright for FOS/RD even with the 0.1" aperture.)
 Therefore we use FOS/RD with a 0.1" square aperture for all parts of this
 program. ---- The first step is a multi-stage peakup acquisition.  The core of
 Eta Carinae is slightly diffuse and has several components in emission-line
 light, all within a size of the order of 0.3". The small aperture size is
 unconventional for the coarse stages of the peakup;  but existing PC and FOC
 images, and a successful Cycle 1 peakup on the same target, indicate that our
 planned acquisition will indeed locate the peak or "centroid" of light. This
 peakup position will then be used as a convenient reference position for
 offsetting to other nearby target positions, all within 1". ---- Following the
 peakup acquisition, we observe a selected set of target locations, with
 separations of the order of 0.15"   and acquired by offsets from the reference
 position.  These targets will not be cleanly resolved from each other, given the
 HST's p.s.f.  However, we will use specialized computer analyses of the entire
 set in order to disentangle the spectral components later (primary star, ejected
 knots, etc). An individual exposure time of only 2 minutes will give high S/N
 ratios for each of these bright target locations.  We will use grating G570H for
 every target;  gratings G400H and G780H will also be used for as many of the
 targets as possible. (G400H is a late addition to the program, intended to
 partially compensate for a recently-discovered ST pointing error in the cycle 1
 FOS/BL observations.)
                                                                  Page   3
------------------------------------------------------------------------------------
  4. Justification of need for HST observations.
  Spatial resolution is the advantage of ST for this project. The "components" of
 Eta Carinae (primary star, blobs of ejecta, conceivably fainter companion stars)
 are separated by only 0.1 to 0.2".  Ground-based speckle techniques can provide
 images but not detailed spectroscopic information on each component. --
 Ironically, this project is possible only because of the ST's optical defect,
 even though high spatial resolution is a goal. If the HST's primary mirror were
 optically correct, then the FOS/RD count rates for our targets would be too high.
 --- Regarding COUNT RATES and exposure times: Cycle 1 FOS/BL observations of the
 peakup location showed that the 5000 A continuum flux through the 0.3" aperture
 (i.e., including the effect of aperture throughput) was about 6e-13 erg cm-2 s-1
 A-1.  The flux through the 0.1" aperture should be smaller by a factor of roughly
 0.3 (a compromise between the point-source and extended-source cases).  The
 expected count rate with grating G570H is then of the order of 400 counts/s per
 diode at 5000 A.  The count rate would be less than 200 at long wavelengths,  and
 more than 1000 in the peaks of several emission lines.  A 2-minute exposure would
 therefore give a range of 15000--150000 counts per diode at the peakup target
 location, except in the very bright H-alpha emission line.   --- The brightest
 emission in this object is the H-alpha line. The cycle 1 FOS/BL observations
 showed a maximum flux of about 6e-12 erg cm-2 s-1 A-1 getting through the 0.3"
 aperture at the peak of H-beta (H-alpha is not accessible with FOS/BL).  The line
 width implicit here is largely instrumental (2 or 3 diodes). According to ground-
 based observations as well as theoretical considerations, the H-alpha emission is
 roughly 8 times as bright as H-beta, i.e. its peak would have been 5e-11 erg cm-2
 s-1 A-1 through the 0.3" FOS aperture, or 1.5e-11 through the 0.1" aperture that
 we plan to use with FOS/RD. This gives a peak count rate of about 13000 or 22000
 counts/s per diode, using grating G570H or G780H respectively.  Count rates like
 this would occur in only 2 or 3 diodes, the apparent line width. --- The
 continuum and peak count rates discussed above refer to the peak-up target
 location;  the outlying targets should be fainter by factors of about 3. ---
 Since it is difficult to describe our target brightnesses in terms of point
 sources, in the exposure log we have chosen to specify equivalent surface
 brightnesses instead, including blurring by the p.s.f.  When estimating count
 rates from these numbers, use the aperture area (= 0.01 square arcsec) in place
 of the "throughput" (e.g. "7 percent") used for point sources.
------------------------------------------------------------------------------------
  5. Description of special scheduling requirements.
  We do not have any special scheduling or calibration requests.  The 0.1" FOS
 apertures are seldom used and may be uncalibrated, but we do not need absolute
 fluxes. The instrument orientation angle is not critical for our program.
------------------------------------------------------------------------------------
  6. Description of special calibration exposures.
  No special calibrations are needed (see question 5 above).
                                                                  Page   4
------------------------------------------------------------------------------------
  7. Data reduction and analysis plans.
  Initial reduction of the FOS data should be more or less routine, except that
 the various targets must be treated very uniformly. Rosa and Davidson will share
 the initial data reduction. --- Then, however, subsquent analyses of the overall
 set of data will be very NON-routine and will require far more effort than normal
 for this amount of ST time.  Davidson has already taken some exploratory steps in
 connection with earlier project GO 2338, and will be developing some of the
 necessary programs during summer 1993.  The basic problem is that 2 to 5
 different spectra will be mixed together in each of the target locations, with
 different mixing ratios of course. At present we expect to attempt two different
 approaches. In the first, we use only general ideas about characteristics of the
 different intrinsic spectra: "Given N observed spectra, each of which is a
 different mixture of M intrinsic spectra where M < N, what can we figure out
 about the intrinsic spectra?"  Unique solutions cannot be found but additional
 astrophysical knowledge, e.g. of the differences between continuum and emission-
 line spectra, can help.  In the second, potentially superior approach, we
 construct models of the FOS response as a function of position, consistent with
 the existing images (Ebbets' and Weigelt's ST images, Weigelt's speckle data) and
 with the ST's spatial p.s.f. convolved   with the 0.1" FOS aperture.  In the
 simplest form of this approach we model the object as 3 or 4 point sources;  in
 an ultimate form this approach would be almost like image deconvolution of a
 whole "spectral map".  Davidson, possibly assisted by a student and/or Rosa, will
 undertake these tasks. --- As noted above, Ebbets and especially Weigelt will
 provide high-resolution images needed for the analyses.  Humphreys and Walborn
 will interpret the intrinsic spectrum of the primary star (and also secondary
 stars, if any are found to be present).  Davidson and Rosa will interpret
 emission lines. It is possible that R. Kudritzki and K. Simon in Munich, who were
 CoIs on the related FOS/BL project GO 2338, will collaborate also on the final
 results, e.g. through stellar atmosphere modeling. --- Ultimately, the best
 possible separation of component spectra is so difficult that it will probably
 not be completed within a year of the observations.  Of course we expect to
 publish interim results before that is finally done.
------------------------------------------------------------------------------------
  8. Additional comments or special requests.
  No pertinent additional comments or requirements that we can think of.  As noted
 above, HST imaging results from some other projects will probably be used for the
 data analysis;  some of these images are generally available and CoIs on this
 proposal are obtaining the others.  A "special catalog" of acquisition/guide
 stars for this field, ZZZQ, was prepared by KD several years ago using the
 Minnesota APS machine.
------------------------------------------------------------------------------------
  9. Description of previous HST work.
  --GO 2338, "Spectroscopy of ...Eta Carinae point sources" (Davidson was PI);
 very directly related to this project, because it was a predecessor using FOS/BL
 rather than FOS/RD.  Because of the difficulty of the analysis, and lately
 because of discovery of an ST offsetting error, the results have not yet been
 published even though the spectral data are pretty good. --GTO 1186,
 "Imaging...Eta Car" and other GTO projects of Dennis Ebbets:  some of the images
 will be used in connection with this project.  Otherwise, Ebbets' Eta Car
 projects have been concerned mostly with the diffuse ejecta several arcsec from
 the core of Eta, rather than with this core itself.  Some preliminary results
 have appeared in poster papers at several meetings, e.g. ASP at Madison, WI in
 summer 1992. --GO 3815, "UV Obs...Hubble-Sandage Variables" (Humphreys is PI):
 Not directly related, although the H-S variables are generically related to Eta
 Carinae.  GO 3815 observations have not all been done yet, no publications yet.
 Several of us are involved with GO 3815. --GO 2416, "...super metal poor
 galaxies" (RJ Dufour was PI, KD was a CoI):  not related to this project. --Rosa
 has been involved with number of other GTO projects.

------------------------------------------------------------------------------------
 10. Resources to be supplied by investigator's institution(s).
  Computer infrastructure at Minnesota and ESO will be used for most of the data
 reduction and analysis;  KD will be preparing some of the required special
 computer programs during spring and summer 1993.  Supporting ground-based speckle
 data is provided by Weigelt's group, using ESO telescopes.  A special catalog of
 guide stars, to replace the GSC in the crowded field of Eta Car, has been
 produced by KD using the Automated Plate Scanner at the University of Minnesota
 with various special plates. It is hoped that a student at Minnesota will assist
 with the the FOS-"spectral map" analysis.
