The devouring of stars by black holes may already have been observed,although at a much later stage.It is thought that several months after the event that rips the star apart,its matter starts swirling into the hole itself.It heats up as it does so,releasing ultraviolet light and X-rays.
If stars disrupted near black holes really do explode,then they could in principle allow these events to be detected at a much earlier stage,says Jules Hatpern of Columbia University in New York,US2.It may make it possible to see the disruption of that star immediately if it gets hot enough, he says.
Brassart agrees.Perhaps it can be observed in the X-rays and gamma rays,but its something that needs to be more studied, he says.Supernova researcher Chris Fryer of the Los Alamos National Laboratory in Los Alamos,New Mexico,US3,says the deaths of these stars are difficult to simulate,and he is not sure whether the researchers have proven their case that they explode in the process.
