J/A+A/457/637   UBVJHK synthetic photometry of Galactic O stars (Martins+, 2006)

UBVJHK synthetic photometry of Galactic O stars. Martins F., Plez B. <Astron. Astrophys. 457, 637 (2006)> =2006A&A...457..637M
ADC_Keywords: Stars, early-type ; Stars, O ; Models, atmosphere ; Photometry, UBV ; Photometry, infrared Keywords: stars: fundamental parameters - stars: atmospheres - stars: early-type Abstract: The development of powerful infrared observational techniques enables the study of very extincted objects and young embedded star-forming regions. This is especially interesting in the context of massive stars that form and spend a non negligible fraction of their life still enshrouded in their parental molecular cloud. Spectrophotometric calibrations are thus necessary to constrain the physical properties of heavily extincted objects. Description: Here, we derive UBVJHK magnitudes and bolometric corrections from a grid of atmosphere models for O stars. Bessel passbands are used. Bolometric corrections (BC) are derived as a function of Teff and are subsequently used to derive BC-spectral type (ST) and absolute magnitudes-ST relations. File Summary:
