Type Ia supernovae and chemical evolution of galaxies

, 2002
The cosmic/galactic chemical evolutions have been modeled with the early metal enrichment by Type II supernovae (SNe II) and the delayed enrichment of Fe by Type Ia supernovae (SNe Ia).

Circumstellar Material in Type Ia Supernovae via Sodium Absorption Features

, 2011
Type Ia supernovae are key tools for measuring distances on a cosmic scale. They are generally thought to be the thermonuclear explosion of an accreting white dwarf in a close binary system. The nature of the mass donor is still uncertain.
