abstract:

    line_1:        Nearby binary-star systems with rapid orbital motion are and
    line_2:        will continue to be the principal source of our knowledge
    line_3:        on stellar masses. Owing to its expected high angular
    line_4:        resolution and high-precision astrometric performance, HST
    line_6:        will provide unusual opportunities for binary-star research.
    line_7:        The purpose of this project is to measure with HST/FGS in
    line_8:        the transfer-function mode selected binary stars, primarily
    line_9:        visual pairs at critical phases in their orbits, in order to
    line_10:       improve substantially our knowledge of their orbital
    line_11:       elements.  These results will not only yield improved mass
    line_12:       values for the systems so investigated, but will also serve
    line_13:       as important calibrators for a large body of existing data
    line_14:       on binary-star orbits and stellar masses.

  question:        3
    section:       1
    line_1:        Each observation will consis of two separate sets of ten
    line_2:        individual scans carried out in the multiple scan mode,
    line_3:        i.e., continuous scans with reversal of scan direction
    line_4:        between any two subsequent scans.  The two sets of scans
    line_5:        constituting each observation will be separated by 45 +/-
    line_6:        15 days, i.e., by about 45 +/- deg. in scan-axes
    line_7:        orientations.  A scan rate of 0.04 arcsec/sec and scan
    line_8:        length of 1.2 arcsec per interferometer axis will be used.
    line_9:        The corresponding exposure time will be 300 sec.  For
    line_10:       purposes of S/N calculations, a sample time of 0.025
    line_11:       sec is adopted, corresponding to an effective step-size
    line_12:       of 0.001 arcsec.  One observation (as defined above) is
    line_13:       desired per target during cycle 3.

!

  question:        4
    section:       1
    line_1:        Most of the binary targets selected for HST observation
    line_2:        are expected to have angular separations less than 30 mas
    line_3:        (the current resolution limit for speckle interferometry
    line_4:        with 4-m class telescopes). Several are also fainter than
    line_5:        the current speckle limit.

!

  question:        5
    section:       1
    line_1:        The requirement to obtain scan sets separated by 45 days
    line_2:        +/- 15 days is justified in order to obtain relative
    line_3:        positions of binary-star components with similar or
    line_4:        equal accuracy in two (orthogonal) coordinates. The
    line_5:        (preferable but less likely) alternative is to roll the
    line_6:        spacecraft by 45 +/- 15 deg between sets of scans made
    line_7:        in quicker succession.

!

  question:        7
    section:       1
    line_1:        Data reduction and analysis will be carried out with the
    line_2:        use of algorithms and software developed and already
    line_3:        successfully used by STAT.  The data reduction and anlysis
    line_4:        will be carried out at Lowell Observatory.

!

  question:        10
    section:       1
    line_1:        Computer facilities at STAT members' institutions.

!

  question:        13
    section:       1
    line_1:        Close visual binaries as well as potentially resolvable
    line_2:        spectroscopic and occultation binaries will be observed
    line_3:        for the pupose of measuring relative positions and orbital
    line_4:        motions of their components.  Most of the visual binaries
    line_5:        will be at orbital phases never before observed.
