Zhrnutie
| Popis |
English: A Chandra image of RX J1242-11 obtained on 2001 March 9 shows a single point source in blue. This source is about 200 times fainter than it was when observed with ROSAT 9 years earlier, making it one of the most extreme variability events ever detected in a galaxy. This variability, combined with the extreme brightness of the ROSAT source, and the position of the Chandra source in the middle of a galaxy all point to one explanation, that observers have witnessed accretion onto a supermassive black hole from the debris of a star that was torn apart by tidal forces. |
