Black widow is fattest dead star

摘要

A cannibalistic collapsed star Is growing so fat from the partner It Is slowly devouring that it is likely to be the most massive neutron star yet measured. The observation suggests that neutron stars can grow much bigger than previously thought before collapsing to become a black hole.rnThe star in question is a "black widow" pulsar, a type of rotating neutron star that is highly magnetised. It rotates in tandem with a smaller partner, which its gravitational field slowly destroys.
