Catalog Service: Radial velocities of TX UMa
Description
High-dispersion spectrograms of the interacting close binary TX UMa taken in 1969-73 around the primary minima were used to display the rotational effect of the mass gaining component. The resulting rotational velocity of the gainer is 70.8+/-2.9km/s. The magnitude of the effect points to considerable over-synchronous rotation of the gainer due to direct impact of the gas flow from the loser component onto the surface of the gainer. Some aspects of the secular decrease of the orbital period of the system relevant to this finding are discussed, too.
