ALMA Spots Circumplanetary Disk around Young Star AS 209

Aug 9, 2022 by News Staff

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected the emission from 13CO — measure of the molecular gas distribution...

Multi-wavelength observations of the Ophiuchus star-forming region reveal interactions between clouds of star-forming gas and radionuclides produced in a nearby cluster of young stars. The top image (a) shows the distribution of aluminum-26 in red, traced by gamma-ray emissions. The central box represents the area covered in the bottom left image (b), which shows the distribution of protostars in the Ophiuchus clouds as red dots. The area in the box is shown in the bottom right image (c), a deep near-infrared color composite image of the L1688 cloud, containing many well known prestellar dense-gas cores with disks and protostars.
