Abstract:
Several nearby solar-type dwarfs with variable radial velocity were
monitored to find their spectroscopic orbits. Orbital elements of HIP
179, 1989, 2981, 5276, 6439, 11218, 21443, 96434 are determined, as
well as tentative orbits for HIP 28678 and 41214. We discuss each of
those objects. Three of the four double-lined binaries are twins with
nearly equal components. All four orbits with periods shorter than 10d
are circular, the remaining orbits are eccentric.
Description:
The observations were conducted in 2012 and 2013 at the 1-m telescope
of the Crimean Astrophysical Observatory sited in Simeiz, Crimea.
Radial velocities were measured by the CORAVEL-type echelle
spectrometer, the Radial Velocity Meter.
