Abstract (from CDS):

We present a new library of high-resolution synthetic spectra based on the stellar atmosphere code PHOENIX that can be used for a wide range of applications of spectral analysis and stellar parameter synthesis. The spherical mode of PHOENIX was used to create model atmospheres and to derive detailed synthetic stellar spectra from them. We present a new self-consistent way of describing micro-turbulence for our model atmospheres. The synthetic spectra cover the wavelength range from 500Å to 5.5µm with resolutions of R=500000 in the optical and near IR, R=100000 in the IR and Δλ= 0.1Å in the UV. The parameter space covers 2300K ≤Teff≤12000K, 0.0 ≤logg≤+6.0, -4.0 ≤[Fe/H]≤+1.0, and -0.2 ≤[α/Fe]≤+1.2. The library is a work in progress and we expect to extend it up to Teff=25000K.
