报告摘要:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Type Ia SNe are thermonuclear explosions that destroy white dwarfs. They have been used to map the Universe and discover Dark Energy. Yet, the details of their origin are debated, with different progenitor channels and explosion mechanisms competing for the limelight. In this talk I will discuss some of the common properties of SNe Ia, and show how they can be used to infer the character of the bulk of the events. I will then focus on different types of outliers and discuss the evidence that they represent different channels, which also exist but do not constitute the bulk of the population.
