The Tiberius pipeline, written in Python, extracts and reduces time-series spectra and fits exoplanet transit light curves. Written in Python, the code can extract spectra from all four JWST instruments, ground-based long-slit spectrographs, and Keck/NIRSPEC echelle spectra. The light curve fitting routines in Tiberius can be used as standalone code to fit, for example, HST light curves extracted with other methods.

p-winds produces simplified, 1-D models of the upper atmosphere of a planet and performs radiative transfer to calculate observable spectral signatures. The scalable implementation of 1D models allows for atmospheric retrievals to calculate atmospheric escape rates and temperatures. In addition, the modular implementation allows for a smooth plugging-in of more complex descriptions to forward model their corresponding spectral signatures (e.g., self-consistent or 3D models).
