碩士 === 國立中央大學 === 天文研究所 === 99 === Time-series photometric observations were carried over sixty nights in 2009 using the 81-cm Tenagra telescope in Arizona within the framework of a multi-year survey program of variable stars in open clusters. The analysis of NGC 1513 and NGC 225 was a pilot study of this effort, we also developed the basic algorithms of the eclipsing binary to compute the data points from our observations to understand the characteristics of eclipsing binary stars in NGC 1513 and NGC 225. About the model, we create some invented observation data to prove the accuracy of its. Totally we find the 12 variable stars including 6 eclipsing binaries in NGC 1513 and NGC 225 and get the results of the model fitting of eclipsing binaries.
