|Versatile Software for
VSTAR is an
radiative transfer code developed by Jeremy Bailey at the
New South Wales. VSTAR can be used to predict the spectra
system planets, exoplanets, brown dwarfs and cool stars.
- Line-by-line approach to molecular absorption using a molecular line database that
contains more than 1.6 billion spectral lines.
- Ionization and Chemical Equilibrium model (ICE) to
chemical equlibrium composition, including gas phase
ionized species and the formation of liquid and solid
- Comprehensive treatment of scattering by molecules,
and aerosols, using Mie scattering, T-matrix and other
- Full multiple scattering treatment of radiative transfer
using discrete-ordinate and other methods.
- Includes vector radiative transfer options (full
polarization, 3 or 4 Stokes parameters).
- Prediction of transmission, radiance, flux, polarization
transit spectra at high spectral resolution.
Development of VSTAR began in
initially to support our observations of the solar system
and Venus. A paper describing an early version of VSTAR was
at the Granada Mars Atmosphere Workshop in 2006. VSTAR was
substantially updated during 2009/2010 to extend its
exoplanets, brown dwarfs and cool stars. Polarization
added in 2011.
The current version of VSTAR is described in the following
