Astronomers Witness Star's Destruction by Black Hole

Scientists have observed a massive Wolf-Rayet star in the Cygnus X-3 system being torn apart by a suspected black hole, located 32,000 light-years away. Using the XRISM telescope, a collaboration between Japan's JAXA and NASA, researchers captured detailed data on the interaction between the star and the compact object, revealing extreme energy phenomena and blueshift effects in the gas ejected by the star. While the data supports the presence of a black hole, the true nature of the compact object remains uncertain, prompting further analysis to confirm its identity.

NASA and JAXA's XRISM Mission Unveils Hidden Stellar Secrets

The XRISM observatory, a collaboration between JAXA and NASA, has provided the most detailed X-ray portrait of Cygnus X-3, a binary system featuring a Wolf-Rayet star and a likely black hole. The mission's high-resolution spectrum reveals complex gas dynamics, including the effects of the Doppler shift due to rapid gas motion. This study aims to enhance understanding of the system's structure and confirm the nature of its compact object. The findings will be published in The Astrophysical Journal.
