Slowing Down Type II Migration of Gas Giants to Match Observational Data
Slowing Down Type II Migration of Gas Giants to Match Observational Data
Abstract The mass and semimajor axis distribution of gas giants in exoplanetary systems obtained by radial velocity surveys shows that super-Jupiter-mass planets are piled up at ≳1 au, while Jupiter/sub-Jupiter-mass planets are broadly distributed from ∼0.03 au to beyond 1 au. This feature has not been explained by theoretical predictions. …
