Astrometric Orbits for Hipparcos Stochastic Binaries
Taking advantage of an improved genetic optimization algorithm forfitting unconstrained Kepler orbits to the Hipparcos intermediateastrometric data, we obtain additional orbital solutions for 81Hipparcos stars with previous stochastic (failed) solutions. The sampleincludes astrophysically interesting objects, including the old diskwide binary HIP 754, the nearby AGB star HIP 34922 (L2 Pup),and the nearby M2 dwarf HIP 5496 (GJ 54, at 8 pc from the Sun), whichhas a resolved M dwarf companion.

Speckle Observations of Binary Stars with the WIYN Telescope. III. A Partial Survey of A, F, and G Dwarfs
Two hundred thirty nearby main-sequence stars with spectral types in therange of A to G have been observed by way of speckle interferometryusing the WIYN 3.5 m telescope at Kitt Peak, Arizona. The stars had noprevious mention of duplicity in the literature. Of those observed, 14showed clear evidence of a companion, and 63 were classified assuspected nonsingle based on a power spectrum analysis. The remainingstars discussed show no evidence of duplicity to the limit of thedetection system in high-quality observations. The WIYN Observatory is ajoint facility of the University of Wisconsin-Madison, IndianaUniversity, Yale University, and the National Optical AstronomyObservatory.
