Jan 17, 2024 · The black hole's gravity rips the star to shreds, resulting in a huge burst of radiation. We've observed this happening several times now. But we don't entirely know why it happens—"it ...

Oct 12, 2022 · TDEs are well-known for emitting light when they occur. As a star nears a black hole, gravitational forces begin to stretch, or spaghettify, the star. Eventually, the elongated material spirals around the black hole and heats up, creating a flash that astronomers can spot from millions of light years away.
Jul 11, 2022 · In 2019 tidal disruption, much of star's mass ended up in symmetrical cloud that hid black hole. Date: July 11, 2022. Source: University of California - Berkeley. Summary: In 2019, astronomers ...
Jul 29, 2023 · Example 24.1: The Milky Way’s Black Hole. The size of the event horizon of a black hole depends on the mass of the black hole. The greater the mass, the larger the radius of the event horizon. General relativity calculations show that the formula for the Schwarzschild radius (RS) of the event horizon is.
May 30, 2018 · On rare occasions, actually as rare as once in every 10,000 years for one galaxy, a star passes very close by the supermassive black hole, and the gravity of the black hole tears it apart. This ...
Jun 1, 2018 · As the black hole is eating the stellar gas, a vast amount of radiation is emitted. The radiation is what we can observe, and using it we can understand the physics and calculate the black hole properties. This makes it extremely interesting to go hunting for tidal disruption events." In the past few years, a few dozen candidates for tidal ...

Sep 23, 2019 · These relatively small black holes can also be made through the merger of two dense stellar remnants called neutron stars. A neutron star can also merge with a black hole to make a bigger black hole, or two black holes can collide. Mergers like these also make black holes quickly, and produce ripples in space-time called gravitational waves.
