Double-peaked supernovae offer clues to pre-supernova outbursts

New research helps in understanding the evolution and final stages of massive stars, the role of binary interactions, and the mechanisms behind mass loss, which ultimately affect the properties of the resulting supernova and its remnant. This work also provides insight into the different progenitor masses and the scenarios that could lead to different types of mass loss, shedding light on the complex processes that govern the life cycles of massive stars.
