Abstract

An analysis of spectrum of the secondary star of the cataclysmic variable 1RXS J094432.1+035738 was discussed including the first detection of the secondary star. Radial velocity of the H? emission line and a refinement of the orbital period were also studied using Gauss function. Results gave the features of a cool secondary star which can be modeled with a red dwarf of spectral type M2-1.0+0.5 V at a distance of 433 ± 100 pc.
