New Libraries of Nonlocal Thermodynamic Equilibrium Model Spectra for O and Early-B Stars

Abstract A new set of stellar spectral models is generated from nonlocal thermodynamic equilibrium metal line-blanketed model atmospheres of T. Lanz & I. Hubeny. The new libraries present spectra in the effective temperature range from 15,000 to 55,000 K, for 8 metallicities, Z / Z ⊙ = 2, 1, 0.5, 0.2, 0.1, 0.0032, 0.02, and 0.01; all of them for three microturbulent velocities, v turb = 2, 5, and 10 km s −1 ; between 200 Å and 32 μ m, and with resolution R = 100,000. The wavelength range supports ground-based optical/NIR, Hubble Space Telescope UV to NIR, as well as JWST NIR/MIR wavelength ranges fully. All models have the same vacuum wavelength scale with 739,791 sample points.
