Tidal disruption events

Simulation of a star being torn apart by the tidal forces of a supermassive black hole and a stream of material drawn from it

A star's rapid rotation may explain why flares near a black hole fade away

Hydrodynamic simulations suggest that a star that was spinning rapidly before being captured in orbit around a supermassive black hole loses less material with each pass, so the repeated flares become weaker. The same scenario may also explain

Tidal disruption event TDE 2025abcr revealed a black hole with an estimated mass of about a million solar masses, far from where supermassive black holes are expected to be found. Artificial intelligence tool tuned to search for events outside galactic centers
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.
