A quantitative NLTE analysis of visual and ultraviolet spectra of four helium-rich subdwarf O stars
Markus Schindewolf, Peter Nemeth, Ulrich Heber +4
Hot subdwarfs represent a poorly understood late phase of stellar evolution. While binary evolution plays an important role for B-subdwarfs (sdB), the origin of the He dominated O-…
SHOTGLAS I: The ultimate spectroscopic census of extreme horizontal branch stars in Centauri
Marilyn Latour, Suzanna K. Randall, Annalisa Calamida +2
The presence of extreme horizontal branch (EHB) and blue hook stars in some Galactic globular clusters (GGCs) constitutes one of the remaining mysteries of stellar evolution. In th…
Rotational broadening and conservation of angular momentum in post-extreme horizontal branch stars
G. Fontaine, M. Latour
We show that the recent realization that isolated post-extreme horizontal branch (post-EHB) stars are generally characterized by rotational broadening with values of $V_{\rm rot} \…
Spectral analysis of the He-enriched sdO-star HD 127493
Matti Dorsch, Marilyn Latour, Ulrich Heber
The bright sdO star HD 127493 is known to be of mixed H/He composition and excellent archival spectra covering both optical and ultraviolet ranges are available. UV spectra play a…
