class webbpsf_ext.spectra.planets_sb12(atmo='hy1s', mass=1, age=100, entropy=10.0, distance=10, accr=False, mmdot=None, mdot=None, accr_rin=2.0, truncated=False, base_dir=None, **kwargs)[source]

Bases: object

Exoplanet spectrum from Spiegel & Burrows (2012)

This contains 1680 files, one for each of 4 atmosphere types, each of 15 masses, and each of 28 ages. Wavelength range of 0.8 - 15.0 um at moderate resolution (R ~ 204).

The flux in the source files are at 10 pc. If the distance is specified, then the flux will be scaled accordingly. This is also true if the distance is changed by the user. All other properties (atmo, mass, age, entropy) are not adjustable once loaded.

Parameters

  • atmo (str) –

    A string consisting of one of four atmosphere types:

    • ‘hy1s’ = hybrid clouds, solar abundances

    • ‘hy3s’ = hybrid clouds, 3x solar abundances

    • ‘cf1s’ = cloud-free, solar abundances

    • ‘cf3s’ = cloud-free, 3x solar abundances

  • mass (float) – A number 1 to 15 Jupiter masses (increments of 1MJup).

  • age (float) – Age in millions of years (1-1000)

  • entropy (float) – Initial entropy (8.0-13.0) in increments of 0.25

  • distance (float) – Assumed distance in pc (default is 10pc)

  • accr (bool) – Include accretion (default: False)?

  • mmdot (float) – From Zhu et al. (2015), the Mjup^2/yr value. If set to None then calculated from age and mass.

  • mdot (float) – Or use mdot (Mjup/yr) instead of mmdot.

  • accr_rin (float) – Inner radius of accretion disk (units of RJup; default: 2)

  • truncated (bool) – Full disk or truncated (ie., MRI; default: False)?

  • base_dir (str, None) – Location of atmospheric model sub-directories.
