A new look at the symbiotic star RW Hydrae

Abstract

We present new estimates of the basic stellar parameters of the non-eruptive, eclipsing symbiotic system, RW Hydrae. A set of photometric and spectroscopic data was used to model this object simultaneously from the light and radial velocity curves. With new spectroscopic data we were able to improve previous results known from the literature and derive physical parameters of the system: q=4.2q=4.2, M1=0.8MM_1=0.8 \rm M_\odot, M2=3.4MM_2=3.4 \rm M_\odot, R1=0.2RR_1=0.2 \rm R_\odot, R2=145RR_2=145 \rm R_\odot, a=350Ra=350 \rm R_\odot, and i=75i=75^\circ.
