Unveiling the Surprising Origins of Gravitational Waves: Dying Stars' Cocoons

Researchers from Northwestern University propose that the turbulent cocoons of debris surrounding dying massive stars could be a new and unexpected source of gravitational waves. Using state-of-the-art simulations, they found that these cocoons can emit detectable gravitational waves within the frequency band that the Laser Interferometer Gravitational-Wave Observatory (LIGO) can detect. This suggests that LIGO could potentially detect the first non-binary source of gravitational waves from these cocoons. The researchers call for further investigation into cocoons as a source of gravitational waves, which could provide insights into the inner workings of stars and the properties of jets in stellar explosions.

Detecting Gravitational Waves from Dying Stars is Imminent

Researchers have discovered that the cocoons formed around dying stars are a new source of gravitational waves, which could provide insight into how stars explode. These cocoons are asymmetric, making them detectable with the next generation of detectors. The properties of these cocoons could be linked to the mechanisms that lead to the death of the star. The study is a call to action for the community to look at cocoons as a source of gravitational waves and to learn more about the innermost part of stars and the properties of jets.

"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.

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.
