¶ In the core-accretion formation scenario of gas giant planets, most of the gas accreting onto a planet is likely processed through an accretion shock. This shock sets the forming planet's structure and thus its observable post-formation luminosity, and the radiative feedback can affect the circumplanetary and circumstellar discs thermally ...
