POLLUX is a stellar spectra database proposing access to theoretical data. It mainly provides high resolution stellar synthetic spectra in the optical, the infrared and the ultraviolet spectral domains based on state-of-the-art 1-D (ATLAS, CMFGEN, MARCS, PHOENIX) and 3-D (STAGGER) radiative transfer codes, and performant spectral synthesis codes (SYNSPEC48, CMF_FLUX, TURBOSPECTRUM, PHOENIX, OPTIM3D). Spectral types from O to M are represented fo a large set of parameters: Teff, logg, [Fe/H], [alpha/Fe], specific abundances. Spectral energy distributions are also made available for early spectral types (O and B type stars).
