Fate of supernova progenitors in massive binary systems

Understand

How massive stars end their lives depends on the core mass, core angular momentum, and hydrogen envelopes at death.

• However, these key physical facets of stellar evolution can be severely affected by binary interactions.
• In turn, the effectiveness of binary interactions itself varies greatly depending on the initial conditions of the binaries, making the situation much more complex.
• We investigate systematically how binary interactions influence core-collapse progenitors and their fates.
