When a star wanders too close to a black hole, intense tidal forces rip the star apart. In these events, called &#8220;tidal disruptions,&#8221; some of the stellar debris is flung outward at high speed while the rest falls toward the black hole. This causes a distinct X-ray flare that can last for a few years. NASA&#8217;s Chandra X-ray Observatory, Swift Gamma-ray Burst Explorer, and ESA\/NASA&#8217;s XMM-Newton collected different pieces of this astronomical puzzle in a tidal disruption event called ASASSN-14li, which was found in an optical search by the All-Sky Automated Survey for Supernovae (ASAS-SN) in November 2014. The event occurred near a super-massive black hole estimated to weigh a few million times the mass of the sun in the center of PGC 043234, a galaxy that lies about 290 million light-years away. Astronomers hope to find more events like ASASSN-14li to test theoretical models about how black holes affect their environments.<\/p>\n<p>During the tidal disruption event, filaments containing much of the star&#8217;s mass fall toward the black hole. Eventually these gaseous filaments merge into a smooth, hot disk glowing brightly in X-rays. As the disk forms, its central region heats up tremendously, which drives a flow of material, called a wind, away from the disk.&#8221;<\/p>\n<p>Video credit: NASA&#8217;s Goddard Space Flight Center<\/p>\n<p class=\"MsoNormal\" style=\"margin: 5px;\">&nbsp;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>This artist&#8217;s rendering illustrates new findings about a star shredded by a black hole.
