It is now known that when a massive star collapses under the force of its own gravity, the final fate of such a continual gravitational collapse will be either a black hole or a naked singularity under a wide variety of physically reasonable circumstances within the framework of general theory of relativity. The research of recent years has provided considerable clarity and insight on stellar collapse, black holes and the nature and structure of spacetime singularities. We discuss several of these developments here.

We present an up-to-date review of Big Bang Nucleosynthesis. We discuss the improvements which have been achieved in the past decades on the overall theoretical framework, summarize the impact of new experimental results on nuclear reaction rates.

The role of neutrinos in stars is introduced for students with little prior astrophysical exposure. We begin with neutrinos as an energy-loss channel in ordinary stars and how stars provide information on neutrinos and possible other particles.

The mechanisms which give rise to Hawking radiation are revealed by analyzing pair production. Three problems are considered: pair production in an external electric field, thermalization of a uniformly accelerated detector and accelerated mirrors.

These lectures on non-baryonic dark matter discuss the need for non-baryonic dark matter in light of recent results, and present some of the most popular candidates for non-baryonic dark matter - neutrinos, axions, neutralinos, etc.
