The Calculations of Effective and Color Temperature of Some Stars in M45 Cluster

Abstract

This research was aimed to study the effective and color temperature of some stars in M45 cluster. The data had been collected from Regional Observatory for the Public Nakhon Ratchasima, National Astronomical Research Institute of Thailand (Public Organization). By using photometry technique the analysis and calculation of data were found that the effective temperature of stars lied between 6,207.72723 K and 10,031.9915 K and the color temperature of stars lied between 6,331.9361 K and 10,688.979 K. We can determine that the type of stars is A, B and F spectrum.
