The Intrinsic Temperature and Radiative-Convective Boundary Depth in the Atmospheres of Hot Jupiters

摘要: In giant planet atmosphere modelling, the intrinsic temperature $T_\mathrm{int}$ and radiative-convective boundary (RCB) are important lower conditions. Often in one-dimensional models three-dimensional general circulation it is assumed that similar to of Jupiter itself, around 100 K, which yields a RCB 1 kbar for hot Jupiters. this work, we show inflated radii, hence high specific entropy interiors, Jupiters suggest much higher values. Assuming effect primarily due current heating (rather than delayed cooling), derive an equilibrium relation between $T_\mathrm{eq}$ $T_\mathrm{int}$, showing latter can take values as 700 K. response, moves upward atmosphere. Using models, find RCBs only few bars, rather kilobar typically supposed. This shallower has implications atmospheric structure, vertical horizontal circulation, interpretations phase curves, deep cold traps on cloud formation.
