The ExoMolOP database contains opacity data for over 80 species of molecules of astrophysical interest, suitable for characterizing high-temperature exoplanets or cool stellar and substellar atmospheres. The data are formatted in different ways for different exoplanet atmosphere retrieval codes.
Here we present a publicly available database of opacities for molecules of astrophysical interest named ExoMolOP that has been compiled for over 80 species, and is based on the latest line list data from the ExoMol, HITEMP, and MoLLIST databases. These data are generally suitable for characterising high-temperature exoplanet or cool stellar and substellar atmospheres, and have been computed at a variety of pressures and temperatures, with a few molecules included at room temperature only from the HITRAN database. The data are formatted in di fferent ways for four di fferent exoplanet atmosphere retrieval codes; ARCiS, TauREx, NEMESIS, and petitRADTRANS, and include both cross sections (at R = lambda/Delta lambda= 15 000) and k-tables (at R = lambda/Delta lambda= 1000) for the 0.3-50 mu m wavelength region. Opacity files can be downloaded and used directly for these codes. Atomic data for alkali metals Na and K are also included, using data from the NIST database and the latest line shapes for the resonance lines. Broadening parameters have been taken from the literature where available, or have been estimated from the parameters of a known molecule with similar molecular properties where no broadening data are available.
