Abstract:                                ! Free format text (please update)
    The ejecta from Eta Car (LBV, most luminous star in the
    Galaxy, pre-SN?) comprise the Homunculus nebula, a dense dusty
    bipolar-shaped, predominantly reflection, nebula surrounded by
    a fast-moving fragmented shell. The velocity vectors of these
    fragments point back to Eta Car and indicate an ejection in
    the middle of the last century. Why a single star should eject
    mass in a clearly non-spherically symmetric way is not
    understood, but a deeper understanding can only follow from
    the 3-D geometry of the ejection nebula, the Homunculus. A
    novel method of exploring the 3-D shape of the Homunculus
    through imaging polarimetry is proposed to resolve the
    controversy on its real shape. By imaging the sub-arcsec knots
    and filaments in the Homunculus in polarized light, their
    position along the line of sight can be determined using a
    geometrical model with dust scattering for the nebula. By
    observing at a number of wavelengths, a detailed model of the
    scattering properties of the dust in the Homunculus can be
    made and then applied to determine the geometry. Careful
    selection of the filter passbands in which to perform
    polarimetry will allow the effect of emission lines on
    continuum scattering to be assessed, especially for the knots
    in the close vicinity of Eta Car. The result will be a clearer
    picture of the geometry of the ejection nebula from a massive
    star, thus enabling the fundamental questions of ejection
    mechanisms to be addressed.

     Observing_Description:
         The Homunculus nebula and Eta Carinae will be imaged with the
         WFC+PC chips in five filters together with the Polarizer POLQ
         filter to map the polarization structure at 0.1'' scales. The
         filters have been chosen with regard to wide wavelength
         coverage (to enable a good model of the dust scattering
         function to be determined) and low contamination of scattered
         continuum by emission lines. For each filter and position of
         the Polarizer POLQ, short (order a few sec) and longer 
         100 -- 800s exposures (depending on filter - detector 
         efficiency and nebula surface brightness) would be obtained 
         to give the core unsaturated and deep images of the nebulosity. 
         In addition images without the Polarizer QUAD are to be obtained
         in order to precisely register the polarizer images, since the
         peak position in polarized light may not correspond to the peak
         in total flux on account of scattering in the source. Additional
         exposures without the Polarizer in filters F218W and F953N were
         added to fill unused target visibility. These are very useful
         probes of the scattering efficiency at short and long wavelengths
         respectively. The F953N data will be used to match the HST 
         observations to ground based adaptive optics observations in the 
         near-IR, scheduled on the ESO 3.6m in March 1996.

         In calculating exposure times, the WFPC2 images of the 
         Homunculus (PI Sparks) have been examined, with allowance made
         for the Polarizer. For example, for the F375N filter, an exposure 
         time of 800s per POLQ position angle will result in about 170 ADU's 
         per 0.1''^2 pixel in the faintest outer regions, allowing a 
         percentage polarization accuracy of ~4% per pixel (neglecting 
         systematics). We have adopted strategy 1a of the WFPC2 Science
         Report 95-01 although the calibration results are not yet known 
         with accuracy. Images with POLQ and the filters are taken in
         the PC1, followed by WF2, WF3 and WF4 all with the same orient.
         The aim is for polarization accuracy of 4% or better and a 
         spatial resolution of 0.2''. The former figure is realistic 
         given the high polarization in the Homunculus and the latter 
         figure allows some spatial degradation concomitant on sequential
         placing of the target on the CCD's. The lowest polarization 
         (over Eta Car) is ~3% and the highest ~40%. From the 
         available polarization modelling, typical differences in the 
         polarization of the near and far sides of the shell would be 
         10-20% so that errors of ~5% would enable the science to be 
         done, although our polarimetric experience shows that very high 
         signal ensures that only systematics dominate.
