A quantitative NLTE analysis of visual and ultraviolet spectra of four helium-rich subdwarf O stars

<i>Aims.</i> Hot subdwarf stars represent a poorly understood late phase of stellar evolution. While binary evolution plays an important role for the formation of B-Type subdwarfs (sdB), the origin of the helium dominated subclass of O-Type subdwarfs (He-sdO) is still unknown. We search...
