Scientists find light from supernova SN 2013ge It has been dimmed since 2016, but next to it there is another source of ultraviolet radiation that retains its brightness, so it is a binary system in which one of the stars “survives”.
Analyzing data from Gubble, astronomers found that there was no hydrogen in the supernova, which was surprising. Scientists wondered where it might have gone before it exploded. The study’s authors found that processes in binary systems of massive stars may have some peculiarities: before the supernova explosion, the second star pumped hydrogen from its “neighbors.”

Scientists will now track the further evolution of the surviving star, which could expect two scenarios depending on the distance from the supernova.
- In the first case, it can be ejected from the system, which explains the origin of single supernovae.
- In the latter, it will continue to orbit its companion before merging with it, but scientists say it will take a billion years.
The University of California, Berkeley, said that studying the life cycle of massive stars is important because their nuclei and supernovae make up all the heavy elements.
