Ultraviolet Colors of Subdwarf O Stars
Published online by Cambridge University Press: 14 August 2015
Extract
The group of subdwarf O stars consisting of field stars and some central stars of old planetary nebulae does occupy an intresting place in the HR diagram. Greenstein and Sargent (1974) have tried to establish this place, and conclude that especially the hottest ones need ultraviolet data to improve the values of effective temperature and absolute luminosity.
