"Dying stars' cocoons create gravitational waves"

Researchers at Northwestern University have used computer simulations to show how cocoons of roiling gas spewed from dying stars may produce "impossible to ignore" gravitational waves, according to research presented at the 242nd meeting of the American Astronomical Society. The cocoon is a turbulent blob of gas, formed when the collapsing star's outer layers interact with the high-powered jets released from within. According to the calculations, the ripples created by the cocoon should be easily detectable by LIGO during its next set of observations.

"Cocooned Dying Stars Could Emit Gravitational Waves, Study Shows"

'Cocoons' of debris around dying stars may be a new source of gravitational waves, according to a new study. When massive stars collapse to form black holes, their stellar material forms a cloud-like cocoon of debris, which is a potential source of gravitational waves that has never been investigated before. These elusive space-time ripples are also emitted by the universe's solo members and may even be powerful enough to be picked up by instruments on Earth.

Exploring the Gravitational Waves from Dying Star Cocoons.

Northwestern University researchers suggest that the cocoons of debris surrounding dying massive stars could be a new source of gravitational waves. Using state-of-the-art simulations, the researchers have shown that these cocoons can emit gravitational waves, which should be within the frequency band that the Laser Interferometer Gravitational-Wave Observatory (LIGO) can detect. Astrophysicists have so far only detected gravitational waves from binary systems, but the researchers believe that cocoons are one of the first places to look for non-binary sources of gravitational waves.
