Gravitational Microlensing A powerful method for probing distant stars surface Parisa Sangtarash p sangtarash@outlook com December 21 2019 Department of Physics Isfahan University of Technology Isfahan 84156 83111 IranDegree Master of Science Language FarsiSupervisor Sedighe Sajadian Assist Prof s sajadian@cc iut ac ir AbstractIn this thesis we will first introduce gravitational lensing gravitational microlensing as a kind of gravitationallensing and describe its applications In the first chapter of this thesis we focus on the amplify of source slight in gravitational microlensing We then obtain the coefficient of light amplification over time and plotthe diagram of a light curve for a source At the end of the first chapter we investigate the states that divertthe microlensing light curve from its standard state and investigate how it helps for determining the physicalparameters of the lens and source In Chapter 2 we will explain another non standard light curves that help usidentify the phenomena of gravitational microlensing under different conditions In Chapter 3 we will considerpolarization in gravitational microlensing which will help us to obtain the polarization of the star s surface fromthe resulting images KeywordsGravitational lensing Gravitational Microlensing Light Curve Polarization
