Extended Data Fig. 2: Lomb-Scargle periodogram of tidally-excited oscillations between periapse passages.

Extended Data Fig. 2

The periodogram of the simulation differs from that of the data, showing that different modes are excited most strongly. In the simulation case, we see most of the power near the rotational frequency, while in the data, the 25th harmonic of the orbital frequency is most-strongly excited.
