The most elusive type of black holes can “restart” white dwarfs for a while – a simulation recently conducted on a supercomputer at the Livermore National Laboratory speaks of this.
Scientists have already managed to detect black holes of the light (star) class and supermassive holes (found in the centers of galaxies), but their middle class with a mass of 100-10000 solar masses has so far escaped scientists (there are only a few candidates for such objects).
An article published in the Astrophysical Journal has shown that meeting such a hypothetical object can temporarily re-ignite a thermonuclear reaction in a fading star of a white dwarf class, as well as cause the release of high energy in the form of electromagnetic and gravitational waves.
“It was exciting to see a zombie star resurgence in each of the scenarios of a close encounter we looked at,” said laboratory lead author Peter Annioonos, a laboratory physicist. “But what really captured my imagination was the idea that these powerful events could be seen. If these objects get close, then a zombie star could become a beacon for a never-before-detected class of black holes. ”
