Young Binary Stars Appear to Form Through Disk Fragmentation, Not Chaotic Migration
A new preprint analyzing 51 infant binary systems finds evidence that many close stellar pairs likely formed from a single unstable disk, strengthening the case for disk fragmentation.
Key Takeaways
- A preprint examined 51 infant binary systems to test how close stellar pairs form.
- Researchers used ALMA observations of gas outflows as a proxy for system angular momentum.
