Abstract

The paper analyzes photometric observations and determines the parameters of a young precataclesmic variable with the subdwarf B, HS 2231+2441. During differential processing of observations, the light curves of the object in the V and R bands were constructed. Their model analysis was carried using models of irradiated stellar atmospheres with the combined consideration of the effects of reflection and nonsphericity of the components. As a result of the optimal description of the observed light curves, some of the parameters of the system were redefined: the inclination angle and semi-major axis of the orbit, the radii and masses of the components of HS 2231+2441. The resulting set of parameters is in good agreement with modern ideas about the characteristics of such systems.

HS 2231+2441的光度观测分析

本文分析了光度观测结果，并确定了与亚矮星B HS 2231+2441有关的年轻震前变量的参数。在对观测值进行差分处理的过程中，构造了物体在V波段和R波段的光曲线。他们的模型分析是利用受辐照的恒星大气模型进行的，并综合考虑了反射和各组分的非球性的影响。通过对观测光曲线的优化描述，重新定义了系统的一些参数:轨道倾角和半长轴、HS 2231+2441各分量的半径和质量。所得到的参数集很好地符合关于这类系统特性的现代思想。
