abstract:

    line_1:        The nature of color and population gradients in globular clusters is one of the
    line_2:        major outstanding puzzles in modern globular cluster reseach.  Clusters with
    line_3:        central cusps (collapsed cores) become bluer towards their centers, while no
    line_4:        clear gradients are seen in clusters with King-model morphology.  The effect
    line_5:        involves at least a few percent of the total visible light. The color gradients
    line_6:        seem to be caused by the demise of red giants and/or subgiants, and possibly
    line_7:        an increased number of faint blue objects.  These effects represent a strong
    line_8:        evidence that dynamical evolution of star clusters can physically modify their
    line_9:        stellar populations.  These phenomena are not yet understood, but a population
    line_10:       of centrally concentrated binaries is most likely responsible for them.  The
    line_11:       underlying physical cause of these effects may be also related to the origin
    line_12:       of millisecond pulsars and low mass x-ray binaries in globular clusters.  Star
    line_13:       counts in the UV near the centers of highly concentrated clusters with the HST
    line_14:       can probe the regions where the gradients should be the strongest and which are
    line_15:       very difficult to study from the ground. In addition to extending the counts of
    line_16:       HB and RGB stars into the central regions we expect to find a new population of
    line_17:       faint blue objects near the centers of these clusters, for which tantalizing
    line_18:       hints have been seen in the best-seeing ground-based data, and in the UV colors
    line_19:       measured by the IUE and ANS satellites.

  question:        3
    section:       0
    line_1:        Our proposed sample contains 9 Galactic globular clusters: NGC 4147, 6093,
    line_2:        6284, 6541, 6652, 6681, 6717, and 7099. Most of them have a definitive or
    line_3:        probable PCC morphology, and all are highly concentrated.  Previous space UV
    line_4:        data (IUE or ANS) exist for 6 of them, and all are classified as being "blue"
    line_5:        or "extremely blue" in their FUV colors.  Our proposed observing strategy is
    line_6:        rather simple: for each target cluster, obtain images with the PC and F336W and
    line_7:        F439W filters (roughly U and B), as follows: F336W:  300 sec + 2 x 900 sec +
    line_8:        1200 sec = 3300 sec total; F439W:  100 sec + 300 sec + 400 sec = 800 sec total.
    line_9:        Total integration time per cluster = 4100 sec = 1.14 h These exposure times are
    line_10:       based on the M15 study by Lauer et al. (for F336W), and scaling from the WFPC
    line_11:       Handbook for the F439W exposures.  Lauer et al. just reached the turnoff in an
    line_12:       about equal integration.  Most of our targets are a bit closer, and have
    line_13:       comparable foreground extinction.  The multiplicity of exposures serves to
    line_14:       increase the S/N, and to provide the cosmic ray redundancy. The shortest
    line_15:       exposures are a safeguard against saturation of the brightest stars; the
    line_16:       remaining exposure times are our estimates of the longest exposures which would
    line_17:       avoid saturating too many of the brightest stars.  Saturation of the few
    line_18:       brightest stars is not critical for this project: we wish to measure fainter
    line_19:       blue objects, and mere counting of the bright giants is sufficient. NOTE: We
    line_20:       would like to have the SAME ORIENT ( with small POS TARG offsets ) within a
    line_21:       given cluster, if possible ( however, we will drop any restrictions which
    line_22:       would postpone our observations for more than a couple of months! ) GD 6/22/92

  question:        4
    section:       0
    line_1:        The essential point of this proposal is the ability to resolve stars in very
    line_2:        crowded central regions of highly concentrated globular clusters, and to do it
    line_3:        in the UV.  This is where the gradients should be the strongest.  The sharp
    line_4:        core of the HST PSF makes that task possible.  The seeing even in the best
    line_5:        ground-based observations in the V or R bands is practically never better than
    line_6:        about 0.5 - 0.6 arcsec FWHM, and even that is rare; in the U band, the
    line_7:        situation is a little worse.  The superiority of the HST images of globular
    line_8:        clusters has been already abundantly demonstrated.  The feasibility of this
    line_9:        project can be illustrated by the discoveries of numerous blue stragglers in 47
    line_10:       Tucanae (a highly concentrated cluster, not unlike some of our targets), the
    line_11:       study of M15 by Lauer et al. 1991, etc. We are actively pursuing a program of
    line_12:       ground-based multicolor observations of color and population gradients, from
    line_13:       ESO, Palomar, and other observatories. Some of our data are as good as they can
    line_14:       be, in terms of the seeing, etc.; we are simply getting the data on more
    line_15:       clusters, but cannot get any better angular resolution.  We are also starting a
    line_16:       program of spectroscopy of selected blue stars in some of our clusters, and
    line_17:       several other, subsidiary studies.  Good ground-based multicolor CCD images are
    line_18:       already in hand for all of our target clusters, and will be used to supplement
    line_19:       the HST data, by providing the information from larger radii, where the
    line_20:       crowding effects are less severe. We have analysed archival data obtained with
    line_21:       the IUE and ANS satellites.  Interesting UV color effects have been found, but
    line_22:       even the best IUE data provide only hints that some UV gradients exist.

  question:        7
    section:       0
    line_1:        Our team has combined expertise in dealing with the HST data (King, Meylan,
    line_2:        Djorgovski, and Weir), image processing and deconvolutions (Weir, Djorgovski,
    line_3:        and King), stellar photometry in crowded fields, using versions of both Daophot
    line_4:        and Romafot, (Piotto, King, Djorgovski, and Weir), photometry of globular
    line_5:        clusters (King, Djorgovski, Piotto, and Meylan), theoretical interpretation and
    line_6:        modeling (Phinney and Chernoff), and globular cluster dynamics (King, Meylan,
    line_7:        Chernoff, and Phinney). We plan to process and analyse the data primarly at
    line_8:        Caltech (Djorgovski and Weir), and also at Berkeley (King), Padova (Piotto),
    line_9:        and STScI (Meylan). Theoretical modeling and analysis will be done largely at
    line_10:       Caltech (Phinney) and at Cornell (Chernoff). We already have an extensive set
    line_11:       of software for the task, although more software may need to be written for the
    line_12:       specific problems.  Especially noteworthy is Weir's Maximum Entropy package for
    line_13:       deconvolutions of the HST images.  Considerable computing hardware already
    line_14:       exists at all of our institutions, and we anticipate acquiring a dedicated
    line_15:       workstation at Caltech, which would make the data processing faster and more
    line_16:       cost-effective. To measure the images, we plan to use different
    line_17:       HST-PSF-optimized versions of both Daophot and Romafot.  We will also try to
    line_18:       use the image deconvolutions to provide initial star lists for subsequent
    line_19:       processing by a standard PSF fitting package, such as Daophot or Romafot. Our
    line_20:       main technique for restoring the images is a Bayesian Maximum Entropy based
    line_21:       approach using a two-dimensional direct image deconvolution driver for the
    line_22:       commercial (Gull and Skilling) package MemSys5. This system has been applied
    line_23:       successfully on the actual HST data.

    line_1:        King is a GTO on the FOC team, and is actively involved in several HST
    line_2:        projects.  Meylan is an instrument scientist on the FOC team, and is also
    line_3:        actively involved in several HST projects, as well as in an extensive
    line_4:        instrument and science support.  Both King and Meylan are coauthors on several
    line_5:        HST-based papers now in press.  Djorgovski is a P.I. on two Cycle 1 GO
    line_6:        programs, and a Co-I on another GO proposal.  The data have been received and
    line_7:        are now being analysed.  Other Co-I's on this team are also involved in
    line_8:        different HST projects. Several of us (King, Weir, and Djorgovski) authored or
    line_9:        coauthored several papers dealing with the image processing and deconvolution
    line_10:       of HST data. None of these projects relates directly to this proposal.

    line_7:        adequate research facilities (libraries, etc.) at our institutions. At least
    line_8:        two Caltech graduate students will be involved in this project.
