18 Dec 2001 | | Journal: | Di Stefano, R.; Greiner, J.; Murray, S.; Garcia, M. 2001, ApJ, 551L, 37 | | Subject: | astro-ph | | Abstract: | We point out that the tidal disruption of a giant may leave a luminous (10^35-10^39 ergs/s), hot (10-100 eV) stellar core. The ``supersoft’’ source detected by Chandra at the center of M31 may be such a core; whether or not it is, the observations have shown that such a core is detectable, even in the center of a galaxy. We therefore explore the range of expected observational signatures and how they may be used to (1) test the hypothesis that the M31 source is a remnant of tidal stripping and (2) discover evidence of black holes and disruption events in other galaxies. | | Source: | arXiv, astro-ph/0112434 | | Services: | Forum | Review | PDF | Favorites | |
