Stellar companions can affect planet formation

Stellar companions can affect planet formation

Star system: Gliese 3192 A | Distance from the Sun: 22.4 light years

Study of 66 stars with planets and planet candidates found that those with stellar companions have more false positive planet detections and shorter orbital periods for their planets. This suggests that stellar companions can truncate planet-forming disks and affect planet formation.
