April Flowers for redOrbit.com - Your Universe Online Exploring the universe's most violent events using computer simulations is what Enrico Ramirez-Ruiz does. So in 2012, when the first detailed observations of a star being ripped apart by a black hole were reported in Nature, Ramirez-Ruiz was eager to compare the data to his simulations. This was especially true because he doubted one of the published conclusions: that the disrupted star was a rare helium star. "I was sure it was a...

A strange and violent fate awaits a white dwarf star that wanders too close to a moderately massive black hole. According to a new study, the black hole's gravitational pull on the white dwarf would cause tidal forces sufficient to disrupt the stellar remnant and reignite nuclear burning in it, giving rise to a supernova explosion with an unusual appearance. Observations of such supernovae could confirm the existence of intermediate-mass black holes, currently the subject of much debate...
