Supernova explosions sow galaxies with the elements necessary for life and act as a tracer revealing the fate of the universe to us. Yet for all their importance, these include some sub-types that we all understand. Probably the most confusing people are those who are known as Type Ax (pronounced as one-ax), but the possible remnants of one of these events may provide some great clues for their understanding and it may be the first to be found in the Milky Way.
Before we had, any idea what caused these supernovas – powerful, illuminated stellar explosions classified based on their dominant spectral lines. The most useful of these for research purposes are as type IA that has the very advantageous feature of always being similar in their internal brightness. By measuring how much light we see from type IA supernova astronomers we can get a good idea of how far the explosion is, and that is why the galaxy in which it placed is from us.
This has served enough to reveal that we are accelerating the expansion of the universe, but at first IAs range from one-sixth to one-third, that is not supernovae. This occasionally includes a group called Type Ax Supernovas, which has a spectrum characterized by ionized silicon similar to the typical type year, but is quite dilapidated.
While at the University of Amsterdam, Ping Zhou Chandra, who led the study, observed the remains of a supernova known as the Sagittarius A formerly using the X-ray telescope. Chiu thinks this is the first remnant of the supernova of our item that we found in our galaxy. In addition to the need to weed to measure distances, aixes need some explanation. Ordinary IA supernovae are white dwarf stars earning many products. They believed to combine two white dwarfs, or to involve a white dwarf stealing material from a common star nearby. The favorite theory for IX is that the thermonuclear reaction that causes IA to explode for some reason travels more slowly through the stars, blocking the sharp brightness peak and allowing a white dwarf piece to survive.
We have seen that there is evidence of IX explosions that result in low production of certain components. “In other galaxies we have found type Ax supernovae, but we have not yet found evidence of one in the Milky Way,” Zhou said in a statement. In a study published in the Astrophysical Journal, Zhou and co-authors reported small amounts of elements such as argon and calcium, and the high concentrations of manganese and nickel make it a strong IX candidate.
Finding only IX supernova remains in distant galaxies is an achievement; detailed studies are currently beyond us, so doing a study in comparative proximity is an incredible opportunity. Sagittarius A gets its name from the East because it is located right next to Sagittarius A *, the black hole at the center of our galaxy. It is very close, but only but 26,000 light-years away, we have a lot more to learn than something 100 million light-years away. Furthermore, since Sagittarius A * is one of the most studied objects outside the solar system, our Sagittarius A has a large number of previous images that are about 25 light-squares wide and overlap with A * as seen from Earth.
Among the earlier explanations for the unusual nature of Sagittarius, it was the supernova remnants of the original collapse that were compressed from very close to Sagittarius A’s supermassive black hole, but Zhou argued that it could produce much more calcium and less manganese than observed.
The final proof is that a surviving white dwarf piece can found but it will become clear because of interference from the galactic center.
