High Velocity Spectroscopic Binary Orbits from Photoelectric Radial Velocities: BD +82 565A
A. Bartkevicius, J. Sperauskas
The spectroscopic orbit of a circumpolar high-proper-motion visual binary BD +82 565 A component is determined from 57 CORAVEL radial velocity measurements. A short period P = 12.6…

Radial velocities of population II binary stars. II
A. Bartkevicius, J. Sperauskas
Here we publish the second list of radial velocities for 91 Hipparcos stars, mostly high transverse velocity binaries without previous radial velocity measurements. The measurement…

Hipparcos red stars in the HpV_{T2} and VI_C systems
I. Platais, D. Pourbaix, A. Jorissen +6
For Hipparcos M, S, and C spectral type stars, we provide calibrated instantaneous (epoch) Cousins color indices using newly derived photometry. Three new sets of…
