- Astronomers identified KSP-OT-202104a, a dwarf nova with a 72-minute orbit.
- The system sits below the roughly 76-minute period minimum long used for dwarf novae.
- Only ten such systems are known, and this team found two of them.
- The companion star’s composition or evolutionary state may explain the unusually tight orbit.
