| Abstract: |
Red supergiant stars are characterized by large convection-related
surface structures that cause surface inhomogeneities and shock waves.
We explore the impact of granulation on photocentric and photometric
variability using 3D simulations of convection with Co5BOLD and
the post-processing radiative transfer code OPTIM3D to compute
spectra and intensity maps in the Gaia G band (325 – 1030 nm). |
