New Study On The Ophiuchus Star-Forming Complex In The Solar System

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.

Supernovas in the Ophiuchus star cluster are the most likely source of short-lived radionuclides in the star-forming clouds, according to a new study.

The Ophiuchus star-forming complex offers an analog for the formation of the solar system, including the sources of elements found in primitive meteorites.
