Supernova Research Paper by stephen shea on Prezi.
All stars begin life in the same way. A cloud of dust and gas, also known as a nebula, becomes a protostar, which goes on to become a main sequence star. Following this, stars develop in different.
Named ASASSN-15lh, this object is so bright that “it is 200 times more powerful than the average supernova, 570 billion times brighter than our sun, and 20 times brighter than all the stars in our Milky Way Galaxy combined.” Though it is so bright, the mass of ASASSN-15lh is small, which has puzzled the international team of astronomers that is studying the object.

In new research to appear in Astrophysical Journal, the KU researcher and colleagues argue the estimated distance of the supernova thought to have occurred roughly 2.6 million years ago should be cut in half. “There’s even more evidence of that supernova now,” he said. “The timing estimates are still not exact, but the thing that changed to cause us to write this paper is the distance.
The thermal energy released when the infalling supernova mantle hits the semi-solid core is very large, about 10 53 ergs, about a hundred times the energy released by the supernova as the kinetic energy of its ejected mass. Dozens of research papers have been published in the attempt to describe the hydrodynamics of how that small one percent of the in falling energy is transmitted to the.

The Crab Nebula is the nearest, most conspicuous and appealing supernova remnant. In 1054, a star in the constellation of Taurus exploded in a supernova (the violent death of a star) so bright that it dominated the evening sky for more than a year. (History of the Crab Nebula) The nebula consists of the material ejected in the supernova explosion, which spreads over a volume of 10 light years.
