abstract:

    line_1:        The binary pulsar PSR1913+16, supposedly a prime laboratory for gravitational
    line_2:        radiation, may have an optically visible companion, or may be in a visible
    line_3:        nebula. WFPC and FOC images will be used to improve the optical
    line_4:        astrometry and to study the extension seen in the original images.
    line_5:        Since this is such a uniquely important object for our understanding of
    line_6:        gravitational radiation, it is crucial to make these definitive
    line_7:        observations to clarify the existing uncertainty. If there is an
    line_8:        optically luminous companion, or a nebula surrounding the pulsar,
    line_9:        this will require modifications to the interpretation of the pulsar
    line_10:       timing data.

    line_1:
    line_2:        Clearly the resolution of ST which enabled the faint extension to be
    line_3:        found is the reason for this request to obtain better S:N on this
    line_4:        crucial source. Also, HST resolution makes it much easier to do the
    line_5:        precise astrometry needed for this faint source.

  question:        10
    section:       1
    line_1:        This is a GTO/AUG proposal, and thus the institutional arrangements remain
    line_2:        the same for this as for the GTO science.
