论文摘要
我们介绍了灾难性变量（CV）PTF1J2224+17的时间分辨光度法，该速度在2018年10月和2019年1月从Inastars天文台获得的4晚获得。该对象在103.82分钟的周期内是可变的。档案Catalina实时瞬态调查（CRTS），PTF和ZTF-DATA显示出高和低状态之间的频繁变化。基于其光度法和识别频谱中的回旋子驼峰，该物体无疑被归类为AM Herculis Star（或极性），其可能的磁场强度可能为B〜65 mg。从9年的光度监测估计其增生占空比约为35％。
We present time-resolved photometry of the cataclysmic variable (CV) PTF1J2224+17 obtained during 4 nights in October 2018 and January 2019 from Inastars observatory. The object is variable on a period of 103.82 min. Archival Catalina Real-Time Transient Survey (CRTS), PTF, and ZTF-data show frequent changes between high and low states. Based on its photometric properties and the cyclotron humps in the identification spectrum the object is certainly classified as an AM Herculis star (or polar) with a likely magnetic field strength of B ~ 65 MG. Its accretion duty cycle was estimated from nine years of photometric monitoring to be about 35 %.
