Meet the micronova: Astronomers discovered new type of stellar explosion

#1

Post by smp »


From Ars Technica:
"Astronomers have discovered highly localized thermonuclear blasts coming from the surface of three white dwarf stars—unusually short-lived events they have dubbed "micronovae." They're similar to novas, except these blasts can burn through a tremendous amount of material in just a few hours, roughly equivalent to 3.5 billion Great Pyramids of Giza. According to the authors of a new paper published in the journal Nature, micronovae could be common in the Universe; they're just difficult to detect because they don't last very long."
