A team of Astronomers of the Institute of Astronomy of the University of Hawaii discovered the most explosive cosmic explosions known from the Big Bang. They called them “extreme nuclear transitory” or “Ent”(for its acronym in English).
This phenomenon occurs when a star Massive approaches a supermassive black hole too much and fragmented, releasing an amount of energy without a history.
What most attracted the attention of this discovery is that, these explosions not only have Greater shine than Supernovas; but also that they remain bright during A much longer time.
“We have observed stars destroying as tidal disruption events for more than a decade, but These EDs are different phenomenareaching brightness almost ten times higher than we usually observe, ”he said Jason HinkleResearcher at the Hawaii Institute mentioned.
Ent phenomenon: technical details
According to the publication Spacethe EDs are stars with masses at least three times higher than those of the Sun. While similar events were previously observed, the team led by Hinkle mentioned that the power detected in such a degree, which is enough to talk about a new phenomenon.
He Gaia Space Telescopelaunched with the objective of mapping the Milky Wayhe was the first to capture these flares. In the finding, Gaia registered two events that did not adjust to the known patterns of star explosions: GAIA16AAW and GAIA18CDJthey stood out for their prolonged brightness and by releasing energy much greater than supernovae that are more powerful.
“EVs are not only much brighter than normal tidal disruption events, but remain bright for years, widely exceeding energy production even of the most brilliant supernova explosions,” said Hinkle.
This discovery marked a great advance, especially in the understanding of the processes that occur with black holes and their relationship with nearby stars. He opened a window to study these new phenomena.
