Welcome!

VSPEC (Variable Star PhasE Curve) is an exoplanet modeling suite that combines NASA’s Planetary Spectrum Generator (PSG) with a custom variable star (based on the spotty and xoflares packages).

VSPEC is a general exoplanet observation modeling suite that is built to be modular. VSPEC can simulate phase curves of non-transiting planets, transits, eclipses, and direct-imaging spectroscopy. It uses a noise model from PSG, which is sophisticated enough to simulate realistic data for a variety of scenarios.

The original motivation for VSPEC was to create synthetic datasets of Planetary Infrared Excess (PIE) observations, but the code is much more general.

Authors

VSPEC is maintained by Ted Johnson and the original code was written by Cameron Kelahan. Additional contributions come from Tobi Hammond and the PSG team. For more information, see our author list.

Citation

A paper describing VSPEC and other codes was recently accepted by Astronomy & Computing. More information will be posted here upon publication, but in the meantime, please look for it on arXiv.

Additionally, you can cite the specific version of VSPEC that you are using with the CITATION.cff file in the repository root. Just make sure you select the correct version for reproducibility.
