Top: host star metallicity as a function of planet eccentricity for all warm Jupiters in single-planet systems (blue) and multiplanet systems (orange). Middle: stellar host mass as a function of eccentricity for all warm Jupiters. Bottom: semimajor axis as a function of eccentricity for all warm Jupiters. For all panels, the size of the circles scales with minimum planet mass, ﹩{m}_{p}\sin i﹩.
