Black Hole Consumes Star in Energetic Cosmic Event

Approximately 1.1 billion light-years from Earth, a star was torn apart as it approached a black hole. The event, named AT2024wpp or Whippet, released an immense amount of energy.

Discovery and Initial Observations

The event was first detected through its light at the Zwicky Transient Facility at Palomar Observatory in California. Researchers, including Daniel Perley of Liverpool John Moores University and Anna Ho of Cornell University, have been investigating the phenomenon. The findings will be published in the Monthly Notices of the Royal Astronomical Society. Scientists presented the event at the American Astronomical Society’s annual meeting.

The Tidal Disruption Event

The star, initially 30 times the mass of the Sun, was drawn into the black hole’s gravitational field. As the star approached, tidal forces caused it to be shredded, and the resulting debris formed an accretion disk around the black hole. This material spiraled inward, heated to extreme temperatures, and emitted radiation across the electromagnetic spectrum. The energy released during this process was approximately 400 billion times that of the Sun, surpassing the energy of the most powerful known supernovae.

Characteristics of Whippet

Astronomers suspect the event may be a Luminous Fast Blue Optical Transient (LFBOT), a type of visual event associated with star destruction. Observations from NASA’s Swift satellite and the Liverpool Telescope confirmed the presence of a radiant blue glow and X-rays, characteristics of an LFBOT.

Shockwave and Further Research

Investigations suggest the event was initiated by a shockwave traveling at one-fifth the speed of light into dense gas surrounding the star. This shockwave dissipated within approximately six months. Researchers believe that studying events like Whippet can provide a deeper understanding of black hole behavior and related physics.
