Early Star Formation, Types of Supernovae and Redshifts - A Review

Vibha S Vivek, Sunil Joshi, Karthik Shastry

Abstract: This paper reviews early star formation (Big Bang Nucleosynthesis and Population I stars) and different types of supernovae. The H-R diagram will direct most of the writing of this paper, by differentiating between different types of stars on the spectral scale. We will also investigate the proof for the expanding universe through cosmological and relativistic redshifts. The paper will also cover important background knowledge to understand the latter further.
