Abstract:
The visual A component of the Gliese 586AB system is a double-lined
spectroscopic binary consisting of two cool stars with the exceptional
orbital eccentricity of 0.976. Such an extremely eccentric system may
be important for our understanding of low-mass binary formation.
Precise stellar masses, ages, orbital elements, and rotational periods
are a prerequisite for comparing stellar observations to
angular-momentum evolution models.
Description:
Barycentric radial velocities of Gl 586A. Data from the STELLA echelle
spectrograph (SES), from the ELODIE archive (ELODIE), from the SOPHIE
archive (SOPHIE) and from Duquennoy et al. 1992 (CORAVEL). All
velocities are in the STELLA radial velocity system (see paper).
Secondary velocities are set to -999.99 where they are not available
or not used in the paper (SOPHIE and CORAVEL).
