Perseus's Young Stars Pointed Outward
A 406-object census found outward motions and an age-distance gradient consistent with sequential formation.
Summary
A 406-object census found outward motions and an age-distance gradient consistent with sequential formation.
Using Gaia DR3 astrometry and Bayesian age estimates for 406 young stellar objects, researchers report outward motions, a negative age-distance gradient and alignment with remaining gas in Perseus. The accepted Astronomy & Astrophysics study interprets the pattern as consistent with expansion-triggered sequential star formation, not proof of a single trigger.
Why it matters
