Bibliographic description in the original language

Low mass stellar companions around four giant stars / Yılmaz, M.; Bikmaev, I.; Sato, B.; Selam, S. O.; Galeev, A. I.; Keskin, V.; Izumiura, H.; Irtuganov, E. N.; Kambe, E.; Özavcı, İ.; Melnikov, S. S.; Zhuchkov, R. Ya.; Okada, N. // New Astronomy, Volume 34, p. 108-113.

Annotation

We present three low-mass and one solar mass companions found around four intermediate-mass giants precise radial velocity measurements using the 1.5 m Russian-Turkish Telescope (RTT150) at the TÜBİTAK National Observatory of Turkey (TUG). The stellar parameters, which are effective temperature, surface gravity and metallicity, as well as rotational velocity are obtained from spectral analysis. From the estimated stellar masses, the orbital parameters of the companions are also derived.Our stellar parameters and orbital solutions show that all of these stars are evolved intermediate-mass giants.
