TL;DR

This paper reports the discovery and analysis of a new magnetic cataclysmic variable star, 1RXS J073346.0+261933, identified through X-ray and optical observations, revealing its unusual variability and orbital characteristics.

Contribution

It presents the identification and detailed observational analysis of a new polar cataclysmic variable with unique long-term behavior and a 3.20-hour orbital period.

Findings

Identified as a magnetic cataclysmic variable (polar)

Orbital period determined to be 3.20 hours

Exhibited unusual long-term variability and high X-ray-to-optical flux ratio

Abstract

In course of the search for the optical identifications associated with ROSAT X-ray sources we have found a highly variable object with the very unusual long-term behavior, color indices and high X-ray-to-optical flux ratio. We report the archival photometric light curve from the Catalina Sky Survey, optical spectroscopy from RTT150 and time-resolved photometry from Astrotel-Caucasus telescope. The object appears to be the magnetic cataclysmic variable (polar) with orbital period of P=3.20 hr.
