Notes. For O stars, the luminosity and effective temperature (Teff) are calculated based on the calibration of solar-metallicity O stars of type i, iii, and v (Martins et al. 2005). The calibration for B stars are based on Pecaut & Mamajek (2013). (a)From Povich et al. (2011). (b)From Gagné et al. (2011). (c)The listed luminosity for HD 93 162 is calculated as if it is an O 2.5 I star. However, the luminosity for this star is uncertain and can possibly be five times brighter (Hamann et al. 2006).
