The physics and astrophysics of Type Ia supernova explosions
A supernova is a transient astronomical event of spectacular peak brightness that is associated with an exploding star.Supernovae exhibit a range of observational characteristics that historically has led to a rich set of classifications and sub-classifications.Despite the complexity of the observationally-based supernova taxonomy,we now believe that all supernovae are caused by just one of two basic mechanisms:(i) the collapse of the core of a massive star late in its life,or (ii) a runaway thermonuclear explosion in a white dwarf.The former is termed the core-collapse mechanism,and is powered by gravitational energy;the latter is termed the thermonuclear mechanism,and is powered by the release of nuclear binding energy under explosive thermonuclear burning conditions.The papers in this issue of Frontiers of Physics are concerned with a particular type of supernova that is classified observationally as a Type Ia supernova (which we shall often abbreviate by SNe Ia).
