JIMENEZ-TORRES, Juan J.. 3D modeling of spectra and light curves of hot Jupiters with PHOENIX; a first approach. Rev. mex. astron. astrofis [online]. 2016, vol.52, n.1, pp.69-82. ISSN 0185-1101.

A detailed global circulation model was used to feed the PHOENIX code and calculate 3D spectra and light curves of hot Jupiters. Cloud free and dusty radiative fluxes for the planet HD179949b were modeled to show differences between them. The PHOENIX simulations can explain the broad features of the observed 8 μ,m light curves, including the fact that the planet-star flux ratio peaks before the secondary eclipse. The PHOENIX reflection spectrum matches the Spitzer secondary-eclipse depth at 3.6 μ,m and underpredicts eclipse depths at 4.5, 5.8 and 8.0 μ,m. These discrepancies result from the chemical composition and suggest the incorporation of different metallicities in future studies.
