Overcast on Osiris: 3D radiative-hydrodynamical simulations of a cloudy hot Jupiter using the parametrized, phase-equilibrium cloud formation code EDDYSED

摘要: We present results from 3D radiative-hydrodynamical simulations of HD 209458b with a fully coupled treatment clouds using the EddySed code, critically, including cloud radiative feedback via absorption and scattering. demonstrate that thermal optical structure simulated atmosphere is markedly different, for majority our simulations, when effects, suggesting this important mechanism can not be neglected. Additionally, we further sensitive to only sedimentation efficiency (termed $f_{\textrm{sed}}$ in EddySed), but also temperature-pressure profile deeper atmosphere. briefly discuss large difference between resolved structures work, adopting phase-equilibrium parameterised model, previous work incorporating microphysical although fairer comparison where, example, same list constituent condensates included both treatments, reserved future work. Our underline importance study into potential condensate size distributions vertical structures, as strongly influence impact on Finally, synthetic observations reporting an improved match, over cloud-free observed transmission, HST WFC3 emission 4.5 $\mu$m Spitzer phase curve 209458b. find all cloudy have apparent albedo consistent observations.
