Frame descriptions:
- In a binary system system, one star evolves to a white dwarf
- At some future time, its companion runs out of hydrogen fuel and evolves for a period of time into a giant star. (This is quite usual, our own sun will do this at some point in future).
- As a giant star, the companion is far larger than before. Some of its outer material can be captured by the white dwarf.
- The white dwarf reaches the Chandrasekhar limit of around 1.4 solar masses, and can no longer support itself. It undergoes core collapse and a type 1a supernova event takes place.
