Scientific papers, some recently published, reported on two new discoveries of tidal disruption events in the galaxy. Some researchers noticed a strong evidence of radiation and realized that they were, in fact coming from these two tidal disruption events.
Phys.org, responsible for giving you the latest science and technology news, said that the detection of these tidal disruption events is quite interesting. The Palomar Observatory in San Diego, California is the place where the researchers, who discovered the two tidal disruption events, worked. One discovery of the tidal disruption events is already enough but two consecutively is something quite interesting for these scientists.
For those of you who do not know, tidal disruption happens when a star moves too close to a black hole and starts getting pulled apart by the tidal forces of the black hole. The definition of these tidal disruption events came from the University of Maryland Astronomy Division's site. The site also goes in depth about the explanation of tidal disruption including the emission of radiation by the black hole.
These tidal disruption events or TDEs are important in science as it can help provide answers to scientists who are still looking to know more about black holes. The first tidal disruption event discovery happened in the 1990s, which is fairly recent. The two consecutive discoveries of the tidal disruption events happened last year and they are under surveillance until now. NASA's Swift space observatory and high-tech telescopes helped in observing and surveying these two tidal disruption events.
Every tidal disruption event not only emits radiation but also light due to the heat of the gaseous stars. However, the black hole that caused the TDEs are the lowest in mass yet one of the TDEs emit high levels of ultraviolet radiation that makes it unusual compared to other TDEs. Yet this unusual tidal disruption, because it is so near, can easily be a subject for observation. The science reports say that it has the shortest scale (15 days) and the lowest luminosity.
