Orbits and System Masses of 14 Visual Double Stars with Early-Type Components
This paper presents revised orbits and system masses of 14 visual doublestars, in all of which at least one component is of early spectral type:WDS 00546+1911 (STT 20 AB), WDS 01040+3528 (HO 213), WDS 02039+4220 (STT38 BC), WDS 03503+2535 (STT 65), WDS 06393+4200 (STT 150), WDS08285-0231 (A551 AB), WDS 15088-4517 (SEE 219 AB), WDS 15416+1940 (HU580 AB), WDS 16514+0113 (STT 315), WDS 17104-1544 (BU 1118 AB), WDS19172-6640 (GLE 3), WDS 19411+1349 (KUI 93), WDS 22241-0450 (BU 172 AB),and WDS 23382+5514 (A1493). Star masses were calculated from Hipparcosparallax data whenever the precision was good enough (10 cases);otherwise, dynamical parallaxes were used, except in one case involvingcomponent multiplicity. Other physical and orbital properties of thesestars are also discussed.

Speckle observations of visual and spectroscopic binaries. II
Results are presented from speckle observations carried out for 54visual and 45 spectroscopic binaries by using the 212 cm telescope atSan Pedro Martir Observatory in Mexico on six nights from October 20 toOctober 25, 1988. Fringes in power spectrum of 41 visual andspectroscopic binaries (six newly resolved ones) with angular separationlarger than 0.15 arcsec are obtained. Two spectroscopic binaries, HD41116 and HD 206901, each of which has the third component staradditionally to two stars showing periodic variation of radial velocity,were found.

ICCD speckle observations of binary stars. IV - Measurements during 1986-1988 from the Kitt Peak 4 M telescope
One thousand five hundred and fifty measurements of 1006 binary starsystems observed mostly during 1986 through mid-1988 by means of speckleinterferometry with the KPNO 4-m telescope are presented. Twenty-onesystems are directly resolved for the first time, including newcomponents to the cool supergiant Alpha Her A and the Pleiades shellstar Pleione. A continuing survey of The Bright Star Catalogue yieldedeight new binaries from 293 bright stars observed. Corrections tospeckle measures from the GSU/CHARA ICCD speckle camera previouslypublished are presented and discussed.
