Abstract:
This paper presents revised orbits and system masses of 14 visual
double stars, 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 (STT 38 BC), WDS 03503+2535 (STT 65), WDS 06393+4200
(STT 150), WDS 08285-0231 (A551 AB), WDS 15088-4517 (SEE 219 AB), WDS
15416+1940 (HU 580 AB), WDS 16514+0113 (STT 315), WDS 17104-1544 (BU
1118 AB), WDS 19172-6640 (GLE 3), WDS 19411+1349 (KUI 93), WDS
22241-0450 (BU 172 AB), and WDS 23382+5514 (A1493). Star masses were
calculated from Hipparcos parallax data whenever the precision was
good enough (10 cases); otherwise, dynamical parallaxes were used,
except in one case involving component multiplicity. Other physical
and orbital properties of these stars are also discussed.
