Synthetic Spectra of Irradiated Planets
F. Allard, T. Barman, P.H. Hauschildt
We have used our general atmosphere code \phoenix\ to generate
radiative equilibrium models of irradiated planets located near a dM6
and a G2 primary. The external radiation, as modeled also by
\phoenix\, was explicitly included in the solution of the radiative
transfer equation. A cool ($\teff = 500 {\rm K}$) and a hot ($\teff =
1000{\rm K}$) planet were modeled at various orbital separations from
both the dM6 and the G2 primary. In all scenarios, we compared the
effects of the irradiation in two cases: one where dust clouds form
and remain suspended in the atmosphere and another where dust clouds
form but settle out of the atmosphere. The atmospheric structure and
emergent spectrum strongly depend on the presence or absence of dust
clouds.
