摘要
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).
