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 Pn;
- "k" is followed by 10 times the additional upper atmosphere optical
opacity, as measured in cm2/g;
and
- 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: Fnu
- Column 4: Flam
- Column 5: Fdet (mJy for source at 10 pc)
- Column 6: Wavelength (angstroms)
- Column 7: Fdet smoothed by convolution
- Column 8: Temperature of tau=2/3 photosphere
- Column 9: Temperature of tau=2/3 photosphere smoothed by convolution
- Column 10: Fnu smoothed by convolution
- Column 11: Pressure of tau=2/3 photosphere smoothed by convolution
