The Atmosphere of Subluminous B Stars

Symposium - International Astronomical Union, 1984
8 sdB stars have been analyzed for effective temperatures, gravity and helium content by means of LTE and NLTE model atmospheres (Heber et al., 1983). The analyses are based on the following observations: 1.)B&C IDS spectrograms obtained with ESO's 3.6m and 1.5m telescopes (4250–4800å at 29 å/mm, or, 4000–5000å at 59 å/mm).2.)IUE spectra in low ...
