Some Dead Stars May Harbor Enough Uranium To Set Off a Thermonuclear Bomb

sciencehabit shares a report from Science Magazine: A thermonuclear bomb might be ticking deep in the cores of some dead stars. A new theoretical study traces out how certain stellar corpses known as white dwarfs could accumulate a critical mass of uranium that would trigger a massive supernova explosion. The findings could yield insights into the destruction habits of white dwarfs, which are responsible for creating heavy elements like iron and nickel. White dwarf supernovae light up their surroundings with the power of 5 billion Suns, and astronomers have used them as 'standard candles' to measure vast distances across the cosmos. But such blasts are still not entirely understood, and the new study could account for certain, anomalously dim observations of this type of supernovae. The findings appeared on the preprint server arXiv this month and have been accepted for publication in Physical Review Letters.
