NLTE analyses of sdB stars: progress and prospects
N. Przybilla, M. F. Nieva, H. Edelmann
We report on preliminary results of a hybrid non-LTE analysis of high-resolution, high-S/N spectra of the helium-rich subdwarf B star Feige49 and the helium-poor sdB HD205805. Non-…
HE 0437-5439 -- an unbound hyper-velocity main-sequence B-type star
Heinz Edelmann, Ralf Napiwotzki, Uli Heber +2
We report the discovery of a 16th magnitude star, HE0437-5439, with a heliocentric radial velocity of +723+-3km/s. A quantitative spectral analysis of high-resolution optical spect…
High resolution spectroscopy of bright subdwarf B stars - I. Radial velocity variables
H. Edelmann, U. Heber, M. Altmann +2
Radial velocity curves for 15 bright subdwarf B binary systems have been measured using high precision radial velocity measurements from high S/N optical high-resolution spectra. I…
