WASHINGTON : Astronomers have detected a previously unknown type of stellar explosion called a micronova involving thermonuclear blasts at the polar regions of a type of burned-out star called a white dwarf after it has siphoned material from a companion star.
"The discovery was an unexpected surprise. It goes to show just how dynamic the universe is. These events are fast and sporadic. Finding them requires looking at the right place at the right time," said astronomer Simone Scaringi of Durham University in England, lead author of the study published in the journal Nature.
"Under the conditions in which this is triggered, this fusion is explosive, and the micronova occurs: a thermonuclear 'bomb' goes off," said astronomer and study co-author Paul Groot, who divides his time between Radboud University in the Netherlands and the University of Cape Town and South African Astronomical Observatory.
Each micronova event burns through material the equivalent of one large asteroid, or just over one millionth of Earth's mass, Scaringi said.
