By breaking down the problem into separate regions of varying gravitational strength and combining approximate solutions, researchers were able to derive a solution describing all the oscillatory modes of a neutron star's interior and how they are imprinted on the frequency of gravitational waves.

The discovery of the oval-shaped orbit provides new insights into extreme cosmic objects and highlights the need for updated models and technology to further explore gravitational wave signals in the universe.
