This small-scale eruption happens on the surface of white dwarf stars.
A micronova explosion at the pole of a white dwarf, which is stealing materials from its star companion, in an artist's illustration.Astronomers have identified a new miniature type of star explosion, which occurs on isolated regions of certain star surfaces: They’ve named this nuclear eruption a “micronova.”
“It goes to show how dynamic the night sky is,” Simone Scaringi, an astronomer at Durham University in England and lead author of the study, told[Related:When Scaringi and his team first observed a micronova, they had no idea what they were looking at. They noticed that one white dwarf would burst into light for just 10 hours or so in sporadic moments. But the event was too dim and too short to be a usual nova. They observed similar phenomena on two other white dwarf stars.
