摘要

TIC 137608661是由TESS太空任务发现的一颗新的sdBV+dM反射效应双星，轨道周期为7.21小时。除了最近发表的对该系统的详细研究(Silvotti et al.， 2022)之外，本文还包含了对其倾斜度的进一步讨论。此外，从系统径向速度和Gaia DR3固有运动得到的双星的三维空间速度可以看出，TIC 137608661属于银河系薄盘族。

The sdBV+dM close-to-synchronization binary TIC 137608661: inclination and thin disk population

TIC 137608661 is a new sdBV+dM reflection-effect binary discovered by the TESS space mission with an orbital period of 7.21 hours. In addition to the detailed study of this system that was recently published (Silvotti et al., 2022), this article contains a further discussion on its inclination. Moreover, from the 3D space velocities of the binary obtained from the system’s radial velocity and from the Gaia DR3 proper motion, it is shown that TIC 137608661 belongs to the galactic thin disk population.
