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.
