According to this model, gas giants formed and acquired their mass $M_{\\rm p}$ through planetesimal coagulation followed by the emergence of cores onto which gas is accreted. These protoplanets migrate and attain their asymptotic semi-major axis $a$ through their tidal interaction with their nascent disk. Based on the observed properties of protostellar disks, we generate $M_{\\rm p}$","authors_text":"D. N. C. Lin, S.
