Frequency dependence of the imaginary part (ℑ(k2); top panel) and real part (ℜ(k2); bottom panel) of the Love number of the TRAPPIST-1 planets assuming Earth-like compositions, computed from the profiles presented in Sect. 2.2.1 and Fig. 1. The vertical dotted lines correspond to each planet’s principal excitation frequency (i.e., the mean motion, n) if assumed to be perfectly synchronous.
