Abstract:
In the course of our search for the optical identifications of ROSAT
X-ray sources, we have found a highly variable object with a very
unusual behavior on long time scales, rare color indices, and a high
X-ray-to-optical flux ratio. We present the archival light curve from
the Catalina Sky Survey, optical spectroscopy from RTT150, and
time-resolved photometry from the Astrotel-Caucasus telescope. The
object appears to be a magnetic cataclysmic variable (a polar) with an
orbital period P=3.20h.
Description:
The region of RX J0733.7+2619 was observed in December 2008-January
2009 by T.K. using the private 30-cm Astrotel-Caucasus telescope
located at the Mountain Station of Kazan Federal University.
Both software packages provided the most likely period to be
0.1334(1)d, or 7.50 cycles per day. However, an alternative period
of 0.1395(1)d can not be excluded.
The light curve of J0733.7+2619 is updated in real time and available
at the following location:
