Story summary
- Dr. Matthew Teasdale and Dr. Dimitris Stamatinos published a study showing binary stars foster planet formation over single stars.
- Simulations show an inner chaotic “forbidden zone” where planets cannot form.
- Outside this zone, disc fragmentation quickly creates gas giants larger than Jupiter, with binary-star discs yielding more giants than single-star discs.
- Gravity can eject planets as rogue worlds, making Tatooine-type worlds less rare and observable by James Webb Space Telescope.
