Photometric Analysis of CN Andromeda Short Period Binary Star

In this work, the short period binary system named (CN Andromeda) have been chosen to be analyze with B,V light curves using the PyWD2015-Qt5 program .The physical and geometrical parameters have been gained and contrasted with previous results of workers. Also, the absolute parameters have been established with results that are acceptable with the results of other workers. With good accuracy, the bolometric magnitude and Roche lobe radius have been calculated. .The present result shows that the selected system is over contact. Spot solution parameters for the analysed binary system have been evaluated. The observed light curves exhibit asymmetries and oddities caused by the system.
