Explosion once every 15 years, “blood-sucking” companion-Information Technology

A rare star has been discovered 4,566 light-years from Earth that produces a terrifying display of fireworks every 15 years, possibly due to “vampire” behavior.

According to Science Alert, a research team led by astrophysicist Ruslan Konno of the Electron Synchrotron (DESY) in Germany and the HESS Collaboration looked at the binary star system RS Ophiuchi in the constellation Ophiuchus and finds one in two stars every 15 years creating another star. energy explosion.

The explosion was confirmed to be caused by him “exploding” after every 15 years by greedily sucking matter from his ill-fated friend. Only 10 stars with similar behavior were ever recorded.

The vampire was a white dwarf, and his victim was a red giant like most other vampire binaries. What is unique, however, is that instead of the white dwarf going to eternal death in a supernova form, followed by the final explosion of the two companions, it produces a “burp” in the form of a smaller nova explosion, and becomes nearly eternal.

In particular, while orbiting each other, white dwarfs with respectable gravity have sucked up hydrogen and some other material from the red giant. This material accumulates around the surface of the white dwarf and gradually heats up. Periodically, the mass of matter becomes large enough that the pressure and temperature in the lower layers is sufficient to trigger a thermonuclear explosion, which throws what has been “eaten up” over the last 15 years into space.

Small enough, but the thermonuclear explosion was powerful enough to shoot cosmic rays in the form of gamma radiation in all directions, so powerful that a world 4,566 light-years away like Earth would still pick up the signal.

The HESS Collaboration telescope system, located in Namibia, picked up the signal for this explosion.

The study was just published in the journal Science.
