Astronomers used ALMA to study three young, high-mass stars and found, not the orderly, stable process of accreting new material seen in low-mass stars, but instead a “chaotic mess.” They conclude that their observations support a proposed “disordered infall” model for massive young stars that was supported by earlier computer simulations.

ALMA Finds Possible Sign of Neutron Star in Supernova 1987A
Based on ALMA observations and a theoretical follow-up study, scientists suggest that a neutron star might be hiding deep inside the remains of Supernova 1987A.
Image Release: Stellar Fireworks Celebrate Birth of Giant Cluster

Supergiant Atmosphere of Antares Revealed by Radio Telescopes
An international team of astronomers has created the most detailed map yet of the atmosphere of the red supergiant star Antares.
Astronomers Find Elusive Target Hiding Behind Dust
Some young, still-forming stars are surrounded by regions of complex organic molecules called “hot corinos.” In some pairs of young stars forming together as binary pairs, astronomers found a hot corino around one, but not the other. Guessing that the unseen one might be obscured by dust, researchers studied such a pair with the VLA at radio wavelengths that readily pass through dust, and found the other one.
