论文摘要
最近，Halpern等。在灾难性变量1RXS J230645.0+550816中发现了一个周期为464 s的振荡。我对该对象进行了广泛的光度观察，以阐明这种振荡的连贯性并以高精度测量振荡周期。在2018年和2019年获得了22个晚上的观测。观察总持续时间为110小时。振荡在每个漫长的夜晚都揭示出来，在我所有涵盖15个月的观察结果中都是连贯的。由于观测值的覆盖范围很大，我以高精度确定了振荡周期，即464.45600+\ - 0.00010 s。 The oscillation semi-amplitude was large and showed changes from 41.8+\-1.5 mmag in 2018 to 48.6+\-1.8 mmag in 2019. The oscillation pulse profile was symmetrical with a noticeably wider minimum compared to the maximum and showed no noticeable changes during 2018 and 2019. The high precision of the oscillation period allowed me to derive an oscillation ephemeris with a长期有70年的有效性。该鞘井可用于未来的振荡周期变化。尽管在1RXS J230645.0+550816中尚未检测到短期X射线振荡，但由于464-S振荡的高度相干性，该对象的中间极性很可能。
Recently, Halpern et al. discovered an oscillation with a period of 464 s in the cataclysmic variable 1RXS J230645.0+550816. I conducted extensive photometric observations of this object to clarify the coherence of this oscillation and to measure the oscillation period with high precision. Observations were obtained over 22 nights in 2018 and 2019. The total duration of observations was 110 hr. The oscillation was revealed in each long night of observations and was coherent throughout all my observations covering 15 months. Due to the large coverage of observations, I determined the oscillation period with high precision, which was 464.45600+\-0.00010 s. The oscillation semi-amplitude was large and showed changes from 41.8+\-1.5 mmag in 2018 to 48.6+\-1.8 mmag in 2019. The oscillation pulse profile was symmetrical with a noticeably wider minimum compared to the maximum and showed no noticeable changes during 2018 and 2019. The high precision of the oscillation period allowed me to derive an oscillation ephemeris with a long validity of 70 years. This ephemeris can be used for future studies of oscillation period changes. Although short-period X-ray oscillations have not yet been detected in 1RXS J230645.0+550816, the intermediate polar nature of this object is very probable due to the high degree of coherence of the 464-s oscillation.
