Abstract: This thesis is devoted to the study of various aspects of non-extremal black holes and higher dimensional black-objects. We study these objects as solution of low energy string theory. Mathur's conjecture states that a black hole solution describes an ensemble of microstates each of which is completely regular. We further this program for non-extremal configurations. We first look at the phase transition between a black hole and a black string on a circle and reproduce the essential features from a microscopic analysis. Then we propose a model for the early universe where it is taken to be a ten dimensional torus with branes wrapping various cycles. We work out the evolution of this system analytically. Finally we look at smooth non-extremal solutions of supergravity which are known to have classical instabilities. We reproduce their spectrum and width from microscopic analysis and show that the radiation from them is precisely the hawking radiation which is not suppressed by Planck's constant due to the initial state being very special like a bose-einstein condensate.
