Abstract:                                ! Free format text (please update)
    The HST Fine Guidance Sensors (FGS) have the unique
    astrometric capabilities of revealing faint companions in
    close binary systems, and measuring their position angles and
    component separations with a precision which far exceeds that
    which is possible using any ground based techniques. In
    addition, the intensity data which are produced by the FGS
    PMTs while in fine lock provide high precision relative
    photometry on rapid time scales.  In previous HST observing
    Cycles, while in guiding mode, these FGS data were telemetered
    to the ground at a 1 Hz rate.  In mid Cycle 4 a new telemetry
    format will be adopted for all normal operations which will
    provide these astrometric and photometric data at 40 Hz for
    all guide star acquisitions and periods of active guiding. We
    propose to examine these engineering data, obtained from the
    HST archive, to perform a serendipitous search for stellar
    duplicity to determine the incidence of doubles in the Guide
    Star Catalog as well as the separations, position angles, and
    relative brightnesses of the individual stellar components in
    such binaries.  We will also examine the light curves and
    power spectra of the photometric data in an effort to perform
    an astroseismological survey of these stars, as well as look
    for and characterize variations due to other intrinsic
    mechanisms.
