A Giant Planet Around a Tiny Star Is Testing Theories of How Worlds Form
Astronomers are revisiting TOI-5205b, a Jupiter-mass world orbiting a small M-dwarf, because systems like it do not fit neatly with standard expectations about how planets emerge from protoplanetary disks.
Key Takeaways
- TOI-5205b is a roughly Jupiter-mass planet orbiting a low-mass M-dwarf every 1.6 days.
- Its size and host-star mass strain standard disk-scaling expectations in planet formation theory.
