White dwarfs going supernova detonate like a nuclear bomb, study suggests

(Natural News)
A new study published in the
Physical Review Letters suggests that the remnant cores of dead average-size stars can explode like a nuclear bomb.
Known as white dwarfs, these dense cores are packed with heavy radioactive elements called actinides that can spontaneously undergo nuclear fission – the splitting of atoms. Depending on certain conditions, these cores can eventually undergo uncontrolled fission, culminating in a massive stellar explosion known as a supernova.
“The conditions to build and set off an atomic bomb seemed very difficult. I was surprised that these conditions might be satisfied in a natural way inside a very dense white dwarf,” Charles Horowitz, a nuclear astrophysicist from ....

Bad Astronomy | Can a planet be bigger than its star? Yup. But it's not easy.


[ Have we ever found an exoplanet that was larger than its host star? Is that possible? ]
My first reaction was, Yes! Kinda. And then I thought about it a little more, and realized the answer is actually, Yes! But if you mean a star like the Sun, it s unlikely.
Explaining it would be a bit much for Twitter, but as it happens I have a blog! So here s more about this.
That first reaction of
kinda was due to thinking about a white dwarf. This is the remnant of a star that was once like the Sun but died, shedding its outer layers and leaving only the core behind. That core the white dwarf is only about the size of the Earth. If the star had any planets bigger than Earth orbiting it before it died, it s possible that some will survive, and you get a planet bigger than its star. In fact we ve seen a system like this, so yes, it can happen, and we re done. Easy peasy. ....
