标题： The polar Catalysmic Variable 1RXS J173006.4+033813

摘要： 我们报告了1RXS J173006.4+033813的发现，这是一颗具有120.21分钟周期的极性爆发型激变变星。白矮星 primaries 的磁场为 B = 42+6-5 兆高斯，伴星是一颗 M3 型矮星。该系统在活动态和宁静态都表现出高度对称的双峰光度调制。这些现象由回旋加速辐射束和椭球调制的组合引起。伴星的投影轨道速度 K2 = 390±4 km/s。我们对该系统的距离设定了一个上限，即 830±65 pc。 显示英文摘要

摘要： We report the discovery of 1RXS J173006.4+033813, a polar cataclysmic variable with a period of 120.21 min. The white dwarf primary has a magnetic field of B = 42+6-5 MG, and the secondary is a M3 dwarf. The system shows highly symmetric double peaked photometric modulation in the active state as well as in quiescence. These arise from a combination of cyclotron beaming and ellipsoidal modulation. The projected orbital velocity of the secondary is K2 = 390+-4 km/s. We place an upper limit of 830+-65 pc on the distance.
