The orbital solution and dynamical masses of the binary system V* PX Virginis

Wang, Xiaoli; Fu, Yanning; Xia, Fang

V* PX Vir is a nearby single-lined spectroscopic binary with the primary being a variable of a BY Dra-type star. It has a period of ~216 d and the components of the system are two low-mass pre-main-sequence stars. By a simultaneous least-squares fit to the radial velocities, the relative positions, and the revised Hipparcos intermediate astrometri…
