1308.0252 (Peter Nemeth et al.)

Synthetic spectra for O and B type subdwarf stars    [PDF]

Peter Nemeth, Roy Østensen, Pier-Emmanuel Tremblay, Ivan Hubeny
We present a grid of optical (3200--7200 \AA) synthetic spectra calculated with Tlusty/Synspec. The new NLTE model atmospheres include the most recent hydrogen Stark broadening profiles; were calculated in opacity sampling and limited to pure H/He composition. The grid covers the observed parameter space of (He-)sdB and (He-)sdO stars, therefore it is suitable for the homogeneous spectral analyses of such evolved stars.
