With iris, disk emission lines are modeled using isothermal plane-parallel slabs, with a detailed wavelength-dependent opacity treatment that accounts for overlapping lines and optical-depth saturation effects. The line profiles can include turbulent, thermal, and Keplerian broadening.

iris is vectorized and optimized with jax, i.e. the code is dynamically compiled and can (but does not need to) be significantly sped-up using GPUs. We can generate a full JWST MIRI-MRS model spectrum, including multiple species and temperature gradients in a few millisec.
