ExoJAX

Differentiable spectral modelling of exoplanets/brown dwarfs/M dwarfs using JAX! Read the docs 🐕 or deepwiki for ExoJAX.

In short, ExoJAX allows you to do gradient based optimizations, HMC-NUTS, and SVI using the latest database.

ExoJAX Classes

Databases (exojax.database) : *db (mdb: molecular, adb: atomic, cdb: continuum, pdb: particulates)
Opacity Calculators (exojax.opacity) : opa (Voigt profile, CIA, Mie, Rayleigh scattering etc)
Atmospheric Radiative Transfer (exojax.rt) : art (emission w, w/o scattering, reflection, transmission)
Spectral Operator (exojax.postproc) : sop (planet rotation, instrumental broadening, photometry)
Atmospheric Microphysics (exojax.atm) : amp (clouds etc)
