Less than 2 seconds is not a lot of time to find the burst and capture some data. These images show the merger of two neutron stars recently simulated using a new supercomputer model. Redder colors indicate lower densities. Green and white ribbons and lines represent magnetic fields. The orbiting neutron stars rapidly lose energy by emitting gravitational waves and merge after about three orbits, or in less than 8 milliseconds. The merger amplifies and scrambles the merged magnetic field. A black hole forms and the magnetic field becomes more organized, eventually producing structures capable of supporting the jets that power short gamma-ray bursts. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/534058main_NS_six_panel_17/534058main_NS_six_panel_17.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Neutron_Star_Merge_H264_High_960x540/Neutron_Star_Merge_H264_High_960x540.dc.xml Gamma-ray bursts are common, yet random, and fleeting events that have mystified astronomers since their discovery in the late 1960s. Shorter bursts (less than two seconds in duration) are thought to be caused by mergers of binary systems with black holes or neutron stars. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Neutron_Star_Merge_H264_High_960x540/Neutron_Star_Merge_H264_High_960x540.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
