Abstract:A new grid of detailed atmosphere model spectra for hot and moderately cool subdwarf stars is presented. High-resolution spectra and synthetic photometry are calculated in the range from 1000 Å to 10,000 Å using Non-LTE fully line-blanketed atmosphere structures. Our grid covers eight temperatures within 10,000 ≤ T eff [K] ≤ 65,000, three surface gravities in the range 4.5 ≤ log g [cgs] ≤ 6.5, two helium abundances matching two extreme helium-rich and helium-poor scenarios, and two limiting metallicity boundar… Show more
