The Stagger-grid: A grid of 3D stellar atmosphere models - VI. Surface appearance of stellar granulation
Zazralt Magic, Martin Asplund
In the surface layers of late-type stars, stellar convection is manifested with its typical granulation pattern due to the presence of convective motions. The resulting photospheri…
Planet transit and stellar granulation detection with interferometry
Andrea Chiavassa, Roxanne Ligi, Zazralt Magic +3
Aims. We used realistic three-dimensional (3D) radiative hydrodynamical (RHD) simulations from the Stagger-grid and synthetic images computed with the radiative transfer code Optim…
The Stagger-grid: A grid of 3D stellar atmosphere models - V. Fe line shapes, shifts and asymmetries
Zazralt Magic, Remo Collet, Martin Asplund
We present a theoretical study of the effects and signatures of realistic velocity field and atmospheric inhomogeneities associated with convective motions at the surface of cool l…
The Stagger-grid: A grid of 3D stellar atmosphere models - IV. Limb darkening coefficients
Zazralt Magic, Andrea Chiavassa, Remo Collet +1
We compute the emergent stellar spectra from the UV to far infrared for different viewing angles using realistic 3D model atmospheres for a large range in stellar parameters to pre…
The Stagger-grid: A grid of 3D stellar atmosphere models - III. The relation to mixing-length convection theory
Zazralt Magic, Achim Weiss, Martin Asplund
We investigate the relation between 1D atmosphere models that rely on the mixing length theory and models based on full 3D radiative hydrodynamic (RHD) calculations to describe con…
