The Role of Radiating Flows in Giant Planet Accretion
Having detected accretion signatures of forming planets in the PDS 70 system and with several other candidates identified, we are entering an era of new avenues to constrain our theories of gas giant formation. At the same time, actual planetary accretion rates are not well understood from a theoretical point of view due to the range of spatial and temporal scales involved. We know radiative cooling is fundamental to the formation of giant planets (regulating both the formation timescale and the circumplanetary structure) but self-consistently understanding the interplay with hydrodynamics and the resulting accreation remains a challenging task. Here I present a combination of radiation-hydrodynamics simulations and semi-analytic solutions to investigate non-trivial accretion dynamics in one, two and three dimensions.
