Mass–radius diagram for transiting sub-Jovian S-type planets with masses <100 M_⊕. We retrieval planetary masses of single transiting S-type planets in pink with the N-body model; cyan dots are the dynamical masses for those with the same radius. Comparing with the Keplerian model, our N-body fitting results slightly shift TOI-1452 b to the right with higher density, but shift TOI-1201 Ab and Kepler-693 Ab to the left with lower density. Density curves in different colors are adopted from L. Zeng et al. (2016).
