Comparative Study of Different Stellar Tracks and Isochrones
With better understanding of the working physics behind the formation and evolution of stars, it has become increasingly important for observers to use an appropriate set of stellar evolutionary tracks and isochrones with respect to the objects of interest. We present a comparative study of three widely used competent stellar models -- MIST, PARSEC and Siess. We analyze their input physics and the final tracks thus generated, especially focusing on the behaviour of the models during the pre-main sequence phase.
