Astronomers have created the first model for how debris around exploding stars could emit gravitational waves powerful enough to be detected by instruments on Earth.
around the black hole, called an accretion disk, could produce gravitational waves. However, as the simulation continued, the outgoing jet collided with the dying star's collapsing layers of material, heating the debris and ballooning it in an hour-glass shaped structure, also called a stellar cocoon. The results from this simulation showed for the first time that such cocoons of stellar debris emit gravitational waves in detectable frequencies, according to the new study.
"To be honest, I did not look for cocoons, but the cocoons were too strong to ignore so I had to go and study [them]," Gottlieb said at the news conference on Monday."So this was more or less by chance that I started to try to understand their gravitational wave emission."
