Main sequence hot Jupiter hosts with good astrometry

While cooler giant planets are often observed with nonzero eccentricities, the short-period circular orbits of hot Jupiters suggest that they lose orbital energy and angular...尽管观测到的低温巨行星（cooler giant planets）普遍具有非零偏心率，但热木星（Hot Jupiters）的短周期圆轨道表明其轨道能量与角动量发生了损耗……
