Gas streamers reveal how massive young stars gain their mass

Tokyo, Japan (SPX) Aug 21, 2025

A research team led by Kyoto University and the University of Tokyo has identified gas streamers as a key mechanism feeding high-mass young stars, challenging the long-held assumption that large accretion disks are the primary drivers of stellar growth. Massive stars, defined as those more than eight times the mass of our sun, form rapidly despite losing material through stellar winds and
