Search for relativistic companions of "runaway" OB stars.
Abstract
Recent progress in a search for relativistic companions of OB runaways is reported. The outcome of spectroscopic studies of four stars is discussed: HD 188001 (9 Sagittae), HD 201345, HD 214930, and HD 218915. The spectrum variability and possible periodicity in the measured radial velocity have been detected for each star, suggesting that these OB stars may indeed have relativistic companions.
