Descripción
At present, it is well established that previously accepted mass-loss
rates (Ṁ) of luminous OB stars may be overestimated when clumping
is neglected. Our Herschel/PACS Far-Infrared (Far-IR) observations of a
set of OB stars allow us to improve our knowledge of clumping
stratification, constraining clumping properties in intermediate wind
regions. In this work, better sampled clumping structure estimates are
provided for ι Ori, ɛ Ori and ξ Per as well as an
initial estimate of the clumping properties of the wind from τ Sco.
These observations will allow us to obtain reliable mass-loss rates and
improve our understanding of the wind physics.
