Investigation Light Curve Analysis for Short Period Eclipsing Binary CN Andromeda

Abstract

In this article research, drawing and analyzing the light curve of short period binary (SPB) star CN Andromeda (CN And) with B, V, R, and I. Light curve fitting and results for the trajectory parameters of the CN And were obtained and compared with those obtained by previous works. The author will determine the size, luminosity and masse of the Individual star as well as the orbital size and orientation of the binary system. Also calculate the bolometric magnitude, reflection coefficient and absolute parameters for short period binary star. These coefficients are needed when analyzing light curves for eclipsing binary stars analyzed to facilitate getting numerical values for their relative and absolute characteristics. Some parameters are also fixed or calculated during light curve modeling. The graph of the dimmer binary luminosity in one complete orbital period is known as light curve. Furthermore, calculating the bolometric magnitude, reflection coefficients, armpit, and absolute parameters for CN, and these terms are very important for understanding the properties of CN And.
