Resolved double-lined spectroscopic binaries: a neglected source of hypothesis-free parallaxes and stellar masses.

POURBAIX D.

Abstract (from CDS):

Double-lined spectroscopic binaries, once visually resolved (VB-SB2), provide hypothesis-free orbital parallaxes and masses of both components. Unlike eclipsing-spectroscopic binaries for which many accurate masses are already known (Andersen, 1991A&ARv...3...91A; Andersen, 1997, in Bedding T.R., Booth A.J., Davis J. (eds.), Fundamental Stellar Properties: The Interaction between Observation and Theory. Kluwer Academic Publishers), the number of VB-SB2 remains rather small. This paper presents 40 such systems for which published visual observations and radial velocities allow a simultaneous adjustment of both data sets. The precision of the individual masses as well as the evolution of that precision with respect to the published precision is investigated.
