Type Ia and Type Ib supernovae both involve binary star systems.

Question

Quizplus · Accepted Answer

Both Type Ia and Type Ib supernovae involve binary star systems, but they differ in the composition of the companion star. Type Ia supernovae involve a white dwarf star that accretes matter from a companion star until it reaches a critical mass and explodes. Type Ib supernovae involve a massive star that has lost its outer layers, revealing a helium core, and explodes when the core collapses.
