Using Gravitational Waves to Probe the Sun's Interior

Scientists propose using gravitational waves to probe the interior of the Sun, which is too hot and dense for light to penetrate. Asymmetrical spinning neutron stars produce continuous streams of gravitational waves, which can be used to study the Sun's density profile. The Sun's gravitational mass lenses the waves as they pass through it, allowing for accurate measurements. Hundreds of fast-rotating neutron stars pass behind the Sun each year, providing an opportunity to observe their gravitational waves and gain insight into our closest star.
