Story summary

Nicolás Yunes of the University of Illinois and Abhishek Hegade of Princeton University developed a method to interpret the frequency of gravitational waves from neutron star mergers.
The method ties tidal forces during mergers to oscillations imprinted on the waves, revealing the stars’ internal structure.
Their theoretical model proposes a complete set of oscillatory modes, though detection remains challenging.
