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.

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.
