The STAGGER-grid: A grid of 3D stellar atmosphere models: V. Synthetic stellar spectra and broad-band photometry

Chiavassa, A.; Casagrande, Luca; Collet, Remo; Magic, Z; Bigot, Lionel; Thévenin, Frédéric; Asplund, Martin


Context. The surface structures and dynamics of cool stars are characterised by the presence of convective motions and turbulent flows which shape the emergent spectrum. Aims. We used realistic three-dimensional (3D) radiative hydrodynamical simulations from the STAGGER-grid to calculate synthetic spectra with the radiative transfer code OPTIM3D for stars with different stellar parameters to predict photometric colours and convective velocity shifts. Methods. We calculated spectra from 1000 to...[Show more]
