A hydrodynamic code for the treatment of late-type stellar wind flows based on the method of characteristics. (English) Zbl 0669.76148

We describe a time-dependent Eulerian hydrodynamic code based on the method of characteristics which allows the computation of radiating stellar wind flows in tube-like structures on late-type stars. The treatment of boundaries under sub- and supersonic conditions is discussed as is the introduction of shock waves into the atmosphere. Ionization is taken into account. For test and application we study the behaviour to approach limiting shock strength.
