Unraveling Type Ia Supernovae

This chapter explores the intricate mechanics behind type Ia supernovae, focusing on the critical role of white dwarf stars in binary systems. It explains how the accumulation of mass from a companion star leads to a dramatic thermonuclear explosion upon reaching the Chandrasekhar limit. The discussion also contrasts type Ia supernovae with type II supernovae, highlighting their unique lifecycle, energy dynamics, and significance in astronomical measurements.
