Super-earths and mini-neptunes follow different orbital period-eccentricity relations
Ke-Ting Shin, Dong-Sheng An, Ji-Wei Xie +2
Many exoplanets have been observed with radius sizes between that of Earth and that of Neptune and are thus classified into two groups: super-earths (SEs) and mini-neptunes (MNs).…

Short-Period Small Planets with High Mutual Inclinations are more Common around Metal-Rich Stars
Xinyan Hua, Sharon Xuesong Wang, Dongsheng An +7
We present a correlation between the stellar metallicities and the mutual inclinations of multi-planet systems hosting short-period small planets (a/Rs<12, Rp<4Re). We analyzed 89…
