Shock waves in a beta Doradus model

Abstract

The accumulation of observational evidence and interpretation supports the conclusion that beta Doradus has running shock waves in its atmosphere. It is the work by Hutchinson with its predictions for the phases of the shock waves that prompted this author to construct a numerical hydrodynamical model for the atmosphere of beta Doradus. A short description of the procedure of the calculation follows. The results for the beta Doradus model contain a comparison with the observations. It is of particular interest to verify that the atmosphere contains multiple shock waves as suggested by Hutchinson for the ultraviolet observations.
