Abstract:
A total of 3350 objects from the Sixth Catalog of Orbits of Visual
Binary Stars (ORB6) are investigated to validate Gaia Early Data
Release 3 (EDR3) parallaxes and provide mass estimates for the
systems. We show that two-thirds of binaries with a separation of
0.2-0.5 arcsec are left without a parallax solution in EDR3. Special
attention is paid to 521 pairs with the parallax known separately for
each component. We find 16 entries that are deemed to be chance
alignments of unrelated stars. First we show examples of
high-confidence binary systems with significant differences in the
reported parallaxes of their components. Next we conclude that the
reported Gaia EDR3 parallax errors are underestimated, by at least a
factor of 3, for sources with a large renormalized unit-weight error
(RUWE). Parallaxes are needed to estimate stellar masses. Because
nearly 30 per cent of ORB6 entries lack a 5- or 6-parameter solution
in EDR3, we attempt to enrich the astrometric data. Distant companions
of ORB6 entries are revealed in EDR3 by the analysis of stellar proper
motions and Hipparcos parallaxes. Notably, in 28 cases, intrinsic EDR3
parallaxes of the binary components appear to be less reliable than
the parallax of the outer companions. Gaia DR2, The Tycho-Gaia
Astrometric Solution (TGAS) and Hipparcos parallaxes are used when
EDR3 data are unavailable. A synthetic mass-luminosity relationship in
the G band for main-sequence stars is obtained to provide mass
estimates along with dynamical masses calculated via Kepler's third
law.
Description:
Visual binary stars with known orbits are supplied with parallaxes of
various origin including outer third-light components. Masses are
estimated via Kepler's third law and mass-luminosity relation.
tablea2.dat contains resolved systems with well-agreed mass estimates.
tablea3.dat collects available parallaxes and derived masses for all
entries. Also available at https://github.com/chulkovd/ORB6.
