Aspects of Optimization of the Transit Light Curve of the Binary System with a Single Minimum in the Eccentricity Components

A high-precision algorithm for interpreting transit light curves in the model of an eclipsing classical binary star-exoplanet system has been improved for interpretation moving from the variables “eccentricity (e)–periastron longitude (ω)” to the eccentricity components (ecosω,e sinω).The possibilities of interpretation by eccentricity components have been studied. It has been shown that the dependence of the minimum’s
shape on e sinω alone is clearly expressed for small values of e and weakens with increasing e. The linear correlation between the radius value, which is characteristic of any values of e, is shown.
