Descripción
OB stars are very active actors shaping their environment and
contributing to the chemical and dynamical evolution of their host
galaxies. Accurate analyses of massive stars are thus a key ingredient
in our interpretation of the light coming from the Milky Way and nearby
galaxies. These analyses rely in the use of state-of-the-art model
atmospheres, that have to be as realistic as possible. In our project,
we aim at testing the self-consistency of our model atmospheres when
carrying out simultaneous analyses in the optical and the near IR. This
is particularly relevant for our Galaxy, where extinction obscures the
optical wavelengths and the inner OB population can only be studied in
the IR. As a first step, we present stellar parameters for a few objects
derived from the optical spectrum, and compare the resulting NIR
profiles with observational data.
