Extreme weather on close-in gas giants

Hi, thanks for such a nice talk. 
But I have some questions.
1. Do you consider the non-zero albedo while modeling the atmospheric circulation for ultra-hot Jupiters? If yes, then is it varies with dissociation and no-dissociation cases of Hydrogen molecules? 
2. Does albedo have a significant effect on your results?

Hello, thanks for your questions! These idealized models consider absorption only and no scattering, which implies zero albedo.
Nonzero albedo on the zeroth-order reduces the irradiation into the atmosphere and lowers the temperature. I think the first-order effect is to reduce the effects of hydrogen dissociation/recombination on the atmospheric flow with a given equilibrium temperature. It probably shifts the day-night fractional temperature differences VS equilibrium temperature towards slightly towards right in the \DeltaT VS T_eq plot. 
The albedo might also change the temperature-pressure structure a bit. But this aspect is not modeled in our current work. We are updating the model to use nongrey radiative transfer which automatically take care of things related to albedo.
