stroyed,Brassart says.Although the explosion obliterates the star,it saves some.of the starts matter from being de
voured by the black hole.The explosion is powerful enough to hurl much of the stars matter out of the black holes
reach,he says.
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 s0,releasing ultraviolet light and Xrays.
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 Halperu of Columbia University in New York,US.It may make it possible to see
the disruption of that star immediately if it gets hot enough.
Brassart aggress.Perhaps it can be observed in the Xrays 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 Almos,New
Mexic0.US,says the deaths of these stars are difficult to simulate,and he is not sure whether the researchers have
proven their case they exploded in the process.
