A Star Dying by the Wrong Rules

Astronomers have discovered a rare binary star system, KSP-OT-202104a, that completes an orbit in just 72 minutes, defying current stellar evolution models. This discovery challenges the established 'period minimum' for dwarf novae and suggests new, unmapped pathways for stellar death.
Why it matters
This finding forces scientists to rethink fundamental theories about how stars age and interact in binary systems, potentially leading to new discoveries in astrophysics.
How do you watch a star die? If it lives alone, like our Sun, it’s rather more difficult. So when researchers want to understand stellar death, they turn instead to the roughly half of all stars that live in pairs, locked in orbit around a companion. In these binary systems the two stars pull and tear at one another, and that violence tells a story.
