Tidal disruption flares carry important information about how this debris initially settles into an accretion disk.

In a paper published in Astrophysical Journal Letters, researchers from MIT, NASA's Goddard Space Flight Center, and elsewhere report on a «tidal disruption flare» — a dramatic burst of electromagnetic activity that occurs when a black hole obliterates a nearby star.

As extreme as they are, tidal disruption flares are difficult to observe, as they happen infrequently.

To explain these emission «echoes,» the team ran simulations of a tidal disruption flare produced from a black hole obliterating a star.

The researchers studied the first 270 days following the detection of the tidal disruption flare, named ASASSN - 14li.

Astronomers have caught a handful of black holes in the act of eating stars, a process they call «tidal disruption.»

Artist illustration depicting the record breaking «tidal disruption event» (TDE).

Using data from a trio of orbiting X-ray telescopes, NASA's Chandra X-ray Observatory and Swift Satellite as well as ESA's XMM - Newton, researchers found evidence of a massive «tidal disruption event» (TDE).

Astronomers call this a tidal disruption event.

This artist's rendering shows the tidal disruption event named ASASSN - 14li, where a star wandering too close to a 3 - million - solar - mass black hole was torn apart.

It will be stretched until it rips, in a tidal disruption event.

The first known tidal disruption event that formed a relativistic jet was discovered in 2011 by the NASA satellite Swift.

«If these explosions are tidal disruption events — where a star gets sufficiently close to a supermassive black hole's event horizon and is shredded by the strong gravitational forces — then its properties are such that it would be a brand new type of tidal disruption event,» co-author Erkki Kankare, a physicist at Queen's University Belfast in the U.K., said in a press release.

For the first time ever, scientists have been able to observe these «tidal disruption» flares in infrared wavelength by studying how dust particles surrounding black holes absorb and re-emit the light emitted during the death of stars.

Dozens of these so - called tidal disruption events have been detected since the 1990s, but none that remained bright for nearly as long as this one,» Dacheng Lin, a research scientist at the University of North Hampshire and the lead author of the paper, said in a statement.

When a supermassive black hole does exactly that to a star — sphagettifying the burning ball of gas into shreds and devouring it as it comes too close to the black hole's event horizon — the phenomenon is called a tidal disruption event.

This illustration shows a glowing stream of material from a star as it is being devoured by a supermassive black hole in a tidal disruption flare.
