PLANET TRAPS AND PLANETARY CORES: ORIGINS OF THE PLANET–METALLICITY CORRELATION
@article{Hasegawa2014PLANETTA, title={PLANET TRAPS AND PLANETARY CORES: ORIGINS OF THE PLANET–METALLICITY CORRELATION}, author={Yasuhiro Hasegawa and Ralph E. Pudritz}, journal={The Astrophysical Journal}, year={2014}, volume={794} }
Massive exoplanets are observed preferentially around high metallicity ([Fe/H]) stars while low-mass exoplanets do not show such an effect. This so-called planet–metallicity correlation generally favors the idea that most observed gas giants at r < 10 AU are formed via a core accretion process. We investigate the origin of this phenomenon using a semi-analytical model, wherein the standard core accretion takes place at planet traps in protostellar disks where rapid type I migrators are halted…
