标题： Light Curve Analysis Of W-uma Type Binary Systems Rz Umi, Oq Uma, Lp Uma

摘要： 本研究提供了对三个W UMa型密接双星的新、高质量的光学测光观测。 利用Djurasevic的逆问题方法对相应的光变曲线进行了分析。 为了解释光变曲线的不对称性和变化，我们使用了包含成员星上斑点区域的Roche模型。 这些系统的基本参数被推导出来，包括使用q搜索方法确定的质量比。 检查了涉及活动表面区域的假设，例如主星和次星上的暗斑，或由于磁活动或持续质量转移而在颈部区域出现的亮斑，以解释光变曲线中最大值振幅的变化和几乎相等的最小值深度。 利用推导出的轨道和物理参数，为不同的轨道相位构建了三维模型。 显示英文摘要

摘要： This study presents new, high-quality, optical photometric observations of three W UMa type contact binaries. The analysis of the corresponding light curves is made using Djurasevic's inverse problem method. To explain the light curve asymmetries and variations, we used the Roche model that involved regions containing spots on the components. The fundamental parameters of these systems were derived, including the mass ratios determined using the q-search method. Hypotheses involving active surface regions, such as dark spots on the primary and secondary components, or bright spots in the neck region due to magnetic activity or continuous mass transfer between components, were examined to explain the varying amplitudes of maxima and nearly equal minima depths in the light curves. Using the derived orbital and physical parameters, three-dimensional models were constructed for various orbital phases.
