Atmospheric heat redistribution effect on emission spectra of Hot-Jupiters

Hot Jupiters are the most studied and easily detectable exoplanets for transit observations. However, correlation between atmospheric flow emission spectra of such planets is still not understood. Due to huge day-night temperature contrast in hot Jupiter, thermal redistribution through circulation has a significant impact on vertical temperature-pressure structure spectra. In present work, we aim study variation profiles due different amounts heat redistribution. For this purpose, first derive an analytical relation parameter f emitted flux from uppermost layers Jupiter. We adopt three possible values under isotropic approximation as 14,12 23 full-redistribution, semi-redistribution no-redistribution cases respectively calculate corresponding Next, model by numerically solving radiative transfer equations using discrete space theory formalism. demonstrate that both susceptible function. A reduction yields inversion hence increases amount flux. Finally, revisits Jupiter XO-1b profile degeneracy case show non-inversion best explains planet’s observed dayside
