VSTAR Project

Versatile Software for Transfer of Atmospheric Radiation


VSTAR is an atmospheric radiative transfer code developed by Jeremy Bailey at the University of New South Wales. VSTAR can be used to predict the spectra of solar system planets, exoplanets, brown dwarfs and cool stars.

Features of VSTAR
History of VSTAR

Development of VSTAR began in 2002, initially to support our observations of the solar system planets Mars and Venus. A paper describing an early version of VSTAR was presented at the Granada Mars Atmosphere Workshop in 2006. VSTAR was substantially updated during 2009/2010 to extend its applicability to exoplanets, brown dwarfs and cool stars. Polarization capability was added in 2011.


The current version of VSTAR is described in the following paper:
