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.

NASA Study Suggests Young Sun-Like Stars Calm Down Faster Than Expected

A study using NASA’s Chandra X-ray Observatory found that young Sun-like stars in several clusters emit far less X-ray radiation than expected, a result that could improve prospects for life on nearby planets.

Key Takeaways

NASA says young Sun-like stars are dimmer in X-rays than previously thought.
The study examined eight clusters aged 45 million to 750 million years.

NASA Study Finds Young Sun-Like Stars Quiet Down in X-Rays Faster Than Expected

New Chandra observations suggest young stellar cousins of the Sun lose intense X-ray output more quickly than expected, a result that could improve the odds for life on planets orbiting them.

Key Takeaways

Chandra observations show young Sun-like stars emit fewer X-rays than expected over time.
A faster decline in X-ray activity may improve the odds that nearby planets retain atmospheres.
