Description
  • Spočetli jsme vícesložkové hydrodynamické modely zářením urychlovaného větru hvězd spektrálního typu B. Naše modely se skládají ze čtyř složek, vodíku, helia, urychlovaných iontů a elektronů. Pro všechny složky řešíme rovnici kontinuity, pohybovou rovnici a rovnici pro energii a započítáváme vzájemné srážky. Ve výsledných modelech se objevuje podstatný ohřev třením. Výsledky našich výpočtů naznačují, že vysvětlení heliové chemické pekuliarity prostřednictvím oddělování se helia od zbytku větru je nepravděpodobné. (cs)
  • We calculate hydrodynamic multicomponent models of radiatively driven winds in B type stars. Our wind models consist of four components, namely hydrogen, helium, accelerated ions, and electrons. We solve equations of continuity, motion, and energy for all components and we take into account mutual collisions. Resulting models show large heating caused by friction. Results of our calculations show that the explanation of helium chemical peculiarity by the helium decoupling from the mean wind is unlikely.
