The Kepler Telescope may not be functional for a long time, but it still provides invaluable information to astronomers. Using data collected by Kepler, researchers SN A star named 2018oh is investigating the star, explaining how, at the end of his life, a massive explosion of your light explodes. 170 million years ago SN 2018 Ho Superno died, but it is far too far because this incident has led us to reach so far.
The death of a star rarely occurs in our galaxy, in which approximately one supernova takes shape in the galaxy-sized galaxy every 50 years. But there are many other galaxies in the universe, and experts estimate that a star dies somewhere every second in the universe. By seeing our galaxy and outside other galaxies, scientists can study your mortality after millions of years after that.
Now a team of Australian National University (ANU) has collected data from Kepler Telescope and ground-based telescopes, which is to know more about SN 2018oh. It is a type I supernova, which is a supernova type found in binary systems (two stars which circulate each other), where there is a white dwarf from the stars. White dwarf stars are limited by how much of their companion binary stars they can absorb, especially when they turn slowly, and if they absorb a very large amount, they explode when they reach the ignition temperature for carbon fusion .
Researchers believe that SN In the case of 2018oh, this explosion process was even more dramatic than usual. Generally, Type I SuperNova shines for about three weeks before fading, but SN This process has been faster with 2018oh – in a few days it has been brighter and extinct. The chief researcher in the study, Dr. Bread Tucker guessed that another star in the binary system might be responsible for this unusual result: "In the case of SN 2018oh, it is possible that the blast flows from the white dwarf. The companion star creates an extremely hot and bright halo, which adds brightness and heat Take into account. "
Dr. Tucker emphasized the importance of Kepler data in his project: "Now the retired Kepler space telescope has changed our outlook on the universe – which shows how many planets around other stars are. We know how to end the star in bright explosions. We have also revolutionized it. "
