Models of Neptune-Mass Exoplanets: Emergent Fluxes and Albedos

A Study of the Fluxes from Model Extrasolar "Neptune" Atmospheres as a Function of Orbital Distance, Stellar Type, and Metallicity

Model Description:

The 28 directories in the tarball at the bottom of this page contain the output of the 28 models by the corresponding names in the paper "Models of Neptune-Mass Exoplanets: Emergent Fluxes and Albedos" by D. Spiegel, A. Burrows, L. Ibgui, I. Hubeny, and John A. Milsom (2009). The symbols in the directory and file names have the following meanings:

"T", for temperature, is followed by 0.01 times the star's effective temperature;
"a", for semimajor axis, is followed by 100 times the orbital semimajor axis in AU;
"Z", for metallicity, is followed by the ratio with respect to solar abundance of metals;
"P" is followed by 10 times P_n;
"k" is followed by 10 times the additional upper atmosphere optical opacity, as measured in cm²/g;
the final letter ("G" or "H") indicates whether the radius and surface gravity of the model planet match those of GJ436b or HAT-P-11b.

Each directory is named for each model and is named in the format given above. Directory "XYZ" contains files called XYZ.19, XYZ.20, and XYZ.21. The contents of these files are the following:

XYZ.19:

Column 1: Wavelength (microns)
Column 2: Planet/Star flux ratio
Column 3: Effective geometrical albedo

XYZ.20:

Column 1: Level #
Column 2: DM -- column density (g/cm²)
Column 3: Temperature (K)
Column 4: Pressure (bars)
Column 5: Density (g/cm³)
Column 6: Entropy
Column 7: Rosseland-mean opacity
Column 8: Planck mean opacity
Column 9: Rosseland mean optical depth
Column 10: Distance into the atmosphere from the outside

XYZ.21:

Column 1: Frequency (Hz)
Column 2: Wavelength (microns)
Column 3: F_nu
Column 4: F_lam
Column 5: F_det (mJy for source at 10 pc)
Column 6: Wavelength (angstroms)
Column 7: F_det smoothed by convolution
Column 8: Temperature of tau=2/3 photosphere
Column 9: Temperature of tau=2/3 photosphere smoothed by convolution
Column 10: F_nu smoothed by convolution
Column 11: Pressure of tau=2/3 photosphere smoothed by convolution
