Migration and Growth of Protoplanetary Embryos III: Mass and Metallicity Dependence for FGKM main-sequence stars

Beibei Liu, Xiaojia Zhang, Doug Lin

Radial velocity and transit surveys have found that the fraction of FGKM stars with close-in super-Earth(s) (${\eta }_{\oplus }$) is around $30\%-50\%$, independent of the stellar mass $M…
