Binary Star Orbits From Speckle Interferometry. VIII. Orbits of 37 Close Visual System

Abstract

New orbital elements are presented for 37 close visual systems that have been observed and in some cases discovered by speckle interferometry. Periods of these systems range from 5.7 to 425 yr, semimajor axes from 0".06 to 1".1. Four of these systems (Kui 18, Fin 325, StF 2597, and McA 77) had no previously published orbital analyses, while elements for a number of other systems have undergone major revisions. Finally, 135 new or revised interferometric measurements of these systems are also presented, as well as 8 negative results.
