They conclude that the Saturn core is diffuse.

Saturn's ring oscillations offer a view of the internal structure of the planet, according to an article published in the journal Nature Astronomy. From the data collected by the Cassini spacecraft, Saturn presents a diffuse nucleus with diffuse limits that condition the formation and evolution of the planet.
Normally, the structure of the giant planets is deduced from the study of the gravitational field. However, the influence of the gravitational field is weak in the core, so the consequences are quite limited.
In the research just published, seismic measurements of the rings have been added to the gravity data. As a result, astrophysicists have gained a new vision of the internal structure of the planet. According to him, the nucleus extends to 60% of the planet's radius, much more than in previous calculations. Apparently, the core is diffuse, rather than completely separated and formed exclusively by hydrogen and helium, combining both heavy elements.
According to the researchers, the study of the internal structure of Saturn also serves to investigate other gaseous giants.
