Intermediate-Mass Black Holes
A violent fate awaits a white dwarf star that wanders too close to a moderately massive black hole. According to a new study from the University of California at Santa Cruz, the black hole's gravitational pull on the white dwarf would cause tidal forces sufficient to disrupt the stellar remnant and reignite nuclear...
