Type Ia Supernova Explosions in Binary Systems: A Review

Understand

SNe Ia play a key role in the fields of astrophysics and cosmology.

• It is widely accepted that SNe Ia arise from thermonuclear explosions of WDs in binaries.
• However, there is no consensus on the fundamental aspects of the nature of SN Ia progenitors and their explosion mechanism.
• This fundamentally flaws our understanding of these important astrophysical objects.
