What could rip a star apart? A black hole [ http://www.astronomycafe.net/qadir/abholes.html ]. Giant black holes [ http://imagine.gsfc.nasa.gov/docs/science/know_l2/black_holes.html ] in just the right mass range would pull on the front of a closely passing star much more strongly than on the back. Such a strong tidal force [ http://en.wikipedia.org/wiki/Tidal_force ] would stretch out a star and likely cause some of the star's gasses to fall into the black hole. The infalling gas [ http://antwrp.gsfc.nasa.gov/apod/ap010508.html ] has been predicted to emit just the same blast of X-rays [ http://imagers.gsfc.nasa.gov/ems/xrays.html ] that have recently been seen [ http://www.arxiv.org/abs/astro-ph/0402468 ] in the center of galaxy RX J1242-11 [ http://science.msfc.nasa.gov/headlines/y2004/18feb_mayhem.htm ]. Above [ http://chandra.harvard.edu/photo/2004/rxj1242/more.html#4 ], an artist's illustration [ http://chandra.harvard.edu/resources/illustrations/tidal_disruption.html ] depicts the sequence of destruction [ http://www.xray.mpe.mpg.de/~skomossa/SSU_bg.html ] (assuming that image-distorting gravitational-lens effects [ http://antwrp.gsfc.nasa.gov/htmltest/rjn_bht.html ] of the black hole [ http://antwrp.gsfc.nasa.gov/apod/ap020908.html ] are somehow turned off). Most of the stellar remains would be flung out into the galaxy. Such events are rare, occurring perhaps only one in 10,000 years for typical black holes [ http://antwrp.gsfc.nasa.gov/apod/ap020309.html ] at the center of typical galaxies [ http://antwrp.gsfc.nasa.gov/apod/spiral_galaxies.html ].
