Eccentricity plotted as a function of semimajor axis for all 200 warm Jupiters with new, consistently fit orbits in this analysis. Circles correspond to warm Jupiters in single-planet systems and stars represent warm Jupiters in multiplanet systems. Symbols are colored blue if the warm Jupiter orbits a metal-poor host ([Fe/H] < 0) and orange if they orbit a metal-rich host ([Fe/H] > 0). The gray shaded area shows tracks of constant angular momentum which planets follow during tidal circularization. Here, we have adopted a mass of 1 M_Jup and a radius of 1 R_Jup around a Sun-like star. The dashed black line displays where f-mode tidal dissipation could speed up tidal migration (Y. Wu 2018; J. Dong et al. 2021a).
