The scientist - Hayadan

A general illustration of a star being torn apart by the tidal forces of a black hole. Some of the material forms a hot accretion disk, from which a high-speed wind is emitted. The researchers speculate that a similar mechanism, within a binary system, may explain the AT2024wpp event. Image: NASA's Goddard Space Flight Center/CI Lab.
A black hole probably ripped apart a massive star, creating an unprecedented cosmic flash
The AT2024wpp event, known as the “whip,” reached a brightness of hundreds of billions of suns and evolved at an extraordinary speed. Researchers estimate that a black hole in a binary system ripped apart the companion star, creating a hot accretion disk and rapidly launching a wind.

Illustration of the ambipolar vortex in the protostellar core L1544. The blue lines represent the magnetic field; the red dots are ions and the green dots are neutral molecules. In the inner part of the core, the neutral molecules partially detach from the field and fall towards the center at a higher speed than the ions.
