    The influence of inhomogeneities on hot star wind model predictions

  • Original language description

    We study the effect of wind inhomogeneities (clumping) on O star wind model predictions. For this purpose we artificially include clumping into our stationary NLTE wind models. As a result of the inclusion of optically thin clumps the radiative line force is increased compared to corresponding unclumped models, with a similar effect on either the mass-loss rate or the terminal velocity. When the clumps are allowed to be optically thick in continuum, on the other hand, the radiative force and consequently the mass-loss rate decreases alternatively.

    Vliv nehomogenit na předpovědi rychlosti ztráty hmoty

  • Czech description

    Studujeme vliv nehomogenit (chuchvalců) na předpovědi modelů hvězdných větrů O hvězd. Za tímto účelem zahrnujeme chuchvalce do stacionárních NLTE modelů. V důsledku zahrnutí chuchvalců roste zářivá síla a odpovídajícím způsobem také rychlost ztráty hmotyči konečná rychlost větru. Pokud jsou však chuchvalce opticky tlusté, může docházet k opačnému jevu.
