BINARY STAR ORBITS FROM SPECKLE INTERFEROMETRY .8. ORBITS OF 37 CLOSEVISUAL SYSTEMS

New orbital element are presented for 37 close visual systems that hav e been observed and in some cases discovered by speckle interferometry . Periods of these systems range from 5.7 to 425 yr, semimajor axes fr om 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 elemen ts for a number of other systems have undergone major revisions. Final ly, 135 new or revised interferometric measurements of these systems a re also presented, as well as 8 negative results. (C) 1996 American As tronomical Society.
