We present a V--I color-magnitude diagram for a region 1'--2' the center of M32 based on Hubble Space Telescope WFPC2 images. The broad color-luminosity distribution of red giants shows that the stellar population comprises stars with a wide range in metallicity.
Results are presented of an analysis of V- and I-band HST Planetary Camera images of the giant elliptical galaxy M87 which show that its central starlight distribution is consistent with the black hole 2.6 x 10 exp 9-solar-mass cup model proposed for M87 by Young et al. (1978). A combined approach of image deconvolution and modeling is used to investigate the starlight distribution into limiting radii of about 0.04 arcsec. The central structure of M87 is described by three components: a power-law starlight profile of the form mu(r) varies as r exp -1/4 for r of less than 3 arcsec, a central nonthermal point source, and optical counterparts of the jet knots N1 and M identified by VLBI observations.
The radial velocities of members of Shakhbazian 4 are determined. It is found that the dispersion of the radial velocities is 440 km/s. The apparent and absolute magnitudes of galaxies in V color are obtained. It is found that the M/L ratio of the group is about 220 solar mass/solar luminosity. The crossing time for the Shakhbazian 4 group is equal to 47 Myr.
A wide site of potential astronomical and solar system scientific studies using the wide field planetary camera on space telescope are described. The expected performance of the camera as it approaches final assembly and testing is also detailed.
