再论御夫座FS及其三重激变变系统假说
Revisiting FS Aurigae and its triple cataclysmic variable system hypothesis
摘要：
2011年御夫座FS的长期光变曲线存在一个周期为875天的极长期光变（VLPP）。该周期计算为6个周期。我们重新检查的周期性与新的观测在过去的5年。总共18年的观测证实了第三个机构的长期方式扰动的激变变量（CV）的假设。改进的模型，如偏心和倾斜轨道的第三体和二进制后牛顿修正。我们确认了FS Aur的VLPP，并找到了新的周期857 $\pm$ 78天。当第三体的质量为M=29 MJ时，长期扰动是最有效的，远低于2011年报道的50 MJ。我们估计了第三体对传质速率和系统亮度的影响。我们考虑VLPP的替代方案。新的数据和分析支持FS Aur是三重系统中的CV的假设。
英文摘要：
A very long term variability (VLPP), with period of 875 days, was observed in the long-term light curve of FS Aurigae in 2011. This periodicity was calculated on 6 cycles. We re-examine the periodicity with new observations over of the past 5 yrs. A total of 18 yrs of observations confirm the hypothesis of a third body perturbing in a secular way the cataclysmic variable (CV). Improvements to the model such as eccentric and inclined orbits for the third body and a binary post-Newtonian correction are considered. We confirm the VLPP of FS Aur and find the new period of 857 $\pm$ 78 days. The secular perturbations are most efficient when the mass of the third body is M=29 MJ, much less than the 50 MJ reported in 2011. We estimate the effect of the third body on the mass transfer rate and the brightness of the system. We consider alternative scenarios for the VLPP. The new data and analysis supports the hypothesis that FS Aur is a CV in a triple system.
