Open Access Honors Program Thesis
This thesis will provide an analysis of some aspects of gravitational microlensing and the quantitative descriptions used to model the astrophysical systems involved. One aspect of the mathematical description of micro lensing events that is investigated in this thesis is the evolution of micro lensing equations from the formalism of general relativity. The derivation of these equations from those governing general relativity and the bending of light rays in geometric optics is explicitly determined. The relationship between the equations used to model events and the light curves produced is investigated. The effect of degeneracies in the mathematical equations used to describe microlensing events is investigated, through the varying of parameters in the equations and observation of the changes induced in the theoretical light curves generated.
