The Christmas burst, also known as GRB 101225A, was discovered in the constellation Andromeda by Swift's Burst Alert Telescope at 1:38 p.m. EST on Dec. 25, 2010. Two very different scenarios successfully reproduce features of this peculiar cosmic explosion. It was either caused by novel type of supernova located billions of light-years away or an unusual collision much closer to home, within our own galaxy.
Common to both scenarios is the presence of a neutron star, the crushed core that forms when a star many times the sun's mass explodes.
According to one science team, the burst occurred in an exotic binary system where a neutron star orbited a normal star that had just entered its red giant phase. The outer atmosphere of the giant expanded so much that it engulfed the neutron star, which resulted in both the ejection of the giant's atmosphere and rapid tightening of the neutron star's orbit.
Once the two stars became wrapped in a common envelope of gas, the neutron star may have merged with the giant's core after just five orbits, or about 18 months. The end result of the merger was the birth of a black hole and the production of oppositely directed jets of particles moving at nearly the speed of light, which made the gamma rays, followed by a weak supernova. Based on this interpretation, the event took place about 5.5 billion light-years away, and the team has detected what may be a faint galaxy at the right location.
Another team supports an alternative model that involves the tidal disruption of a large comet-like object and the ensuing crash of debris onto a neutron star located only about 10,000 light-years away.
Gamma-ray emission occurred when debris fell onto the neutron star. Clumps of cometary material likely made a few orbits, with different clumps following different paths before settling into a disk around the neutron star. X-ray variations detected by Swift's X-Ray Telescope that lasted several hours may have resulted from late-arriving clumps that struck the neutron star as the disk formed.
