The supernovae usually fade within weeks, due to the explosion ledobódott material but also can shine supernova remnant in thousands of years. What kind of process can provide the energy for this?
Image taken by the Chandra space telescope blisters in mouth Tycho's supernova remnant. Coded low-energy X-rays with a red expanding debris of the explosion, while encrypted high-energy radiation in the blue and heated by the shock wave formed by the electron blisters in mouth shell is drawn out.
The Harvard-Smithsonian Center for Astrophysics research related to Tycho's supernova residues, it was found that the material of an inward, valid for the gas sound speed a thousand blisters in mouth times the moving shock wave heats up, it shines even more brightly today, the X-ray range. The head of the investigation, according to Hiroya Yamaguchi without the inverse blisters in mouth shock wave is not tanulmányozhatnánk the centuries, millennia remnants of supernova explosions.
New star 1572 observed by Tycho Brahe in Cassiopeia constellation in brightness - eloquently refuted gave the sky no change in contemporary faith - the maximum of the Vénuszéval rivaled, and into the open eye visibility (at the time was not yet Telescope, blisters in mouth astronomers disposal) border about a year After fade. We now know that the explosion was a Type Ia, that is related to a double white dwarf component of the system. blisters in mouth
Ledobódott during the cataclysm, medium containing silicon and iron also began to expand about 5 thousand km / s speeds. When I bumped into the surrounding interstellar material of the result of the interaction of two shock wave was set up: the speed of sound is about 300 times the moved further outwards, the other is more than three times bounced back such a rate, that it started to push inward. blisters in mouth The backward shock wave heats the gas inside the supernova remnant, luster, forcing it not only visible, but the X-ray range. So actually the bounce back in shock, which allows the passage of hundreds blisters in mouth of years can study the remains.
The research team studied the Suzaku satellite instruments blisters in mouth of Tycho's remnant blisters in mouth in the X-ray range. They found that the inward shock wave crossing electrons very quickly heat up a not yet completely understood process. Despite the uncertainties, the results blisters in mouth he is the first to provide blisters in mouth clear evidence of efficient, collision-free shock-heating of the electrons by the inverse. Now, of course, but even in the case of Tycho's remnant, but other young supernova remnant sites are planned in similar studies. blisters in mouth
