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.
The observed alignments strongly favored disk fragmentation over turbulent fragmentation followed by inward migration.

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.
Lower-than-expected X-ray output could improve prospects for life on orbiting planets.

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.
The result refines both stellar evolution models and assessments of planetary habitability.

New models connect white dwarf surface magnetism to interior magnetic evidence from starquakes.
The work supports the idea that some stellar magnetism is preserved over long evolutionary timescales.
The result gives astronomers a framework to relate magnetic fields in living stars to those in stellar remnants.

Astronomers discovered an extremely rare, iron-deficient second-generation star that formed from a single Population III supernova
The star's chemical fingerprint provides direct evidence of how the universe's first stars seeded heavy elements
Such stars were detected using high-resolution spectroscopy across databases of millions of stellar spectra
The findings help constrain the mass and explosion energetics of the universe's first stellar generation
