Abstract (from CDS):

We present the results of spectroscopic and photometric studies of a new polar CRTS CSS 130604 J 215427+155714, conducted at the telescopes of the SAO RAS. Analysis of the photometric series of observations allowed to clarify the orbital period of the system, P = 0.0672879d. We build radial velocity curves and trace the intensity variations in the H-beta and H-gamma hydrogen lines and He II 4686 ionized helium line. Based on the H-beta and He II lines we build Doppler maps. It is shown A ionized helium line. Based on the H and He II lines we build Doppler maps. It is shown that the line formation region is localized near the Lagrange point. The following parameter estimates of the system are obtained: The following parameter estimates of the system are obtained: M1=0.83±0.10, M2=0.15±0.01, q=M2/M1=0.18±0.03, i=53±5.
