Single planet formation regime in the high-ionization environment: Possible origin of hot Jupiters and super-Earths

We studied the particle growth in a protoplanetary disk in a high-ionization environment and found that icy planet formation is inactive for a disk with an ionization rate 100 times higher than that of the present Solar System. In particular, in the case of M˙<10−7.4M⊙yr−1, only rocky planet form...
