双星唯象模型检验函数的结构

The Structure of the Test Function for Phenomenological Modelling of Eclipsing Binaries

Mariia G. Tkachenko

摘要:

测试函数对“NAV”(“New Algol Variable”)算法(Andronov,2012年4月)中使用的唯象参数的依赖性。55.. #35360;研究。由于存在局部最小值,最小化的方法包含两个步骤:在4D参数空间中的网格处的“蛮力”最小化,以及使用差分校正的进一步迭代。这种方法代表了一个有效的近似的光变曲线使用的特殊图案(形状)分别为主要和次要的最小值。简要回顾了该方法在混凝土星上的应用。

英文摘要:

The dependence of the test function on the phenomenological parameters used in the "NAV" ("New Algol Variable") algorithm (Andronov, 2012Ap.....55..536A) is studied. Due to a presence of local minima, the method of minimization contains two steps: the "brute force" minimization at a grid in the 4D parameter space, and further iterations using the differential corrections. This method represents an effective approximation of the light curve using the special pattern (shape) separately for the primary and secondary minima. The application of the method to concrete stars is briefly reviewed.
