标题： Filling the gap: the missing eclipses of $γ$ Persei from 2005 and from 2006

摘要： $\gamma$双星Persei是一个长周期（$P \approx 14.6$年）食双星系统。 由于其周期很长，完全理解该系统具有挑战性：迄今为止，文献中仅记录了1990年和2019年的两次主食，而2005年的主食由于当时接近太阳而未被观测到。 我们的目标是通过处理2003年至2011年由太阳质量抛射成像仪（SMEI）收集的准连续光度数据来填补这一空白，这些数据非常适合观测如此明亮的目标。 为了实现这一点，我们首先确定了一个与颜色相关的转换公式，用于将SMEI测量值转换为{\it 盖亚} \textit{G} 星等。 我们对光度进行了各种校正，并提供了$\gamma$双星Persei最长的连续光变曲线。 我们成功检测到了2005年的系统主食，在年度观测结束时伴随伴星的食出阶段。 我们使用PHOEBE前向建模二元系统来预测可能的次级食位置，并在2006年的SMEI观测中成功恢复了次级食。 次级食的存在对轨道构型施加了严格的限制，这对系统的未来研究将是重要的约束条件。 显示英文摘要

摘要： $\gamma$ Persei is a long-period ($P \approx 14.6$ yr) eclipsing binary system. Its period makes it a difficult target to fully understand: so far, only two primary eclipses are known in the literature, from 1990 and from 2019, whereas the 2005 one was missed due to its closeness to the Sun at the time. We aimed to fill in this gap by processing the quasi-continuous photometry collected by the Solar Mass Ejection Imager (SMEI) between 2003 and 2011, which was ideally positioned to observe such a bright targets. In order to do that, we first determined a color-dependent conversion formula from the SMEI measurements into {\it Gaia} \textit{G} magnitudes. We applied various corrections to the photometry and provide the longest continuous light curve of $\gamma$ Persei. We successfully detected the 2005 primary eclipse of the system, with the yearly observations ending during the egress of the companion. We predicted the position of a possible secondary eclipse by forward modeling the binary system with PHOEBE, and successfully recovered the secondary eclipse in the 2006 SMEI observations. The existence of the secondary eclipse puts strong constraints on the orbital configuration, which will be an important constraint for future studies of the system.
