We carried out a photometric and spectroscopic analysis for the eclipsing binary TIC 157376469 using the TESS and LAMOST data. A new linear ephemeris is given. By fitting the light curves and radial velocity curves with the Wilson–Devinney code, it apperas that the binary is composed of two K-type main-sequence stars. The orbit of the binary is slightly eccentric () and the primary is a spotted active star. The masses and radii of the two components are determined to be , , , , respectively. The temperature ratio () is determined to be ∼0.879. Under a assumption that the primary temperature is , comparisons to the PARSEC v1.2 isochrones show that for the primary the radius is oversized of ∼16%, and the effective temperature is cooler of (∼6%). While, the properties of the secondary are almost in agreement with the predictions of the model.

我们使用 TESS 和 LAMOST 数据对日食二元 TIC 157376469 进行了光度和光谱分析。给出了一个新的线性星历。通过用威尔逊-德文尼码拟合光变曲线和径向速度曲线，双星似乎由两颗K型主序星组成。双星的轨道有点偏心（），主星是一颗有斑点的活跃星。两种组分的质量和半径被确定为，，，，分别。温度比 ( ) 确定为 ~0.879。假设主要温度为，与 PARSEC v1.2 等时线的比较表明，初级半径超大了约 16%，有效温度较低（约 6%）。同时，次级的属性几乎与模型的预测一致。
