Rapid Oscillations in Cataclysmic Variables. XVII. 1RXS J070407+262501
摘要：
我们提出了一个研究最近发现的中间极性1 RXS J 070407 +262501，其大幅度脉冲信号在P = 480秒的区别。径向速度表明轨道周期为0.1821（2）d，光变曲线表明为0.18208（6）d。时间序列测光显示，自转周期精确为480.6700（4）s，以0.096（9）ms/yr的速率递减，即在时间尺度P/P-dot =2.5 x 10^6 yr上。光变曲线在P = 0.263 d处也显示出一个神秘的信号，这可能意味着在这个磁灾变变星中存在一个“超级驼峰”。
英文摘要：
We present a study of the recently discovered intermediate polar 1RXS J070407+262501, distinctive for its large-amplitude pulsed signal at P = 480 s. Radial velocities indicate an orbital period of 0.1821(2) d, and the light curves suggest 0.18208(6) d. Time-series photometry shows a precise spin period of 480.6700(4) s, decreasing at a rate of 0.096(9) ms/yr, i.e. on a time scale P/P-dot =2.5 x 10^6 yr. The light curves also appear to show a mysterious signal at P = 0.263 d, which could possibly signify the presence of a "superhump" in this magnetic cataclysmic variable.
