3D models of AGB stars


The following movies depict numerical 3D simulations of asymptotic giant branch (AGB) stars, highlighting different aspects and properties of the resulting models. The CO5BOLD radiation hydrodynamical code is used to model the interior and inner atmosphere. These are 3D star-in-a-box calculations, describing the variability of AGB stars through self-excited pulsations.

The stellar parameters for the star in the movies are 1 solar mass, 6890 solar luminosity and effective temperature of 2727K. The models have been calculated by Bernd Freytag, at Uppsala University.
