Description
  • Samostatně se objevující absorpční složky profilů (DAC) běžně pozorované v ultrafialových čarách vznikajících ve hvězdném větru horkých hvězd byly modelovány prostřednictvím hydrodynamických simulací tzv. spolurotujících interagujících oblastí (CIR). Metoda kinematické inverze DAC Browna a kol. byla testována na analýze uměle vytvořených CIR modelů. Docházíme k závěru, že ačkoliv je inverzní metoda schopna získat přesné hodnoty hustoty větru v hustotním proudu pouze v blízkosti hvězdy, je s její pomocí možné obdržet hodnotné informace o rychlosti středního větru a sledovat pohyb rychlostního plata v hydrodynamických datech.

  • The Discrete Absorption Components (DACs) commonly observed in the ultraviolet lines of hot stars have previously been modelled by dynamical simulations of Corotating Interaction Regions (CIRs) in their line-driven stellar winds. Here we apply the kinematic DAC inversion method of Brown et al. to the hydrodynamical CIR models and test the reliability of the results obtained. We conclude that the inversion method is able to recover valuable information on the velocity structure of the mean wind and to trace movement of velocity plateaux in the hydrodynamical data, though the recovered density profile of the stream is correct only very near to the stellar surface.
