Testing MURaM and MPS-ATLAS against the quiet solar spectrum
Veronika Witzke, Alexander I. Shapiro, Nadiia M. Kostogryz +8
Three-dimensional (3D) radiative magnetohydrodynamics (MHD) simulations are the only way to model stellar atmospheres without any ad hoc parameterisations. Several 3D radiative MHD…
Modeling Stellar CaII H & K Emission Variations: Spot Contribution to the S-index
K. Sowmya, A. I. Shapiro, L. H. M. Rouppe van der Voort +2
The S-index is a measure of emission in the CaII H & K lines and is a widely used proxy of stellar magnetic activity. It has been assumed until now that the S-index is mainly affec…
Forward modelling of brightness variations in Sun-like stars -- II. Light curves and variability
N. -E. Nèmec, A. I. Shapiro, E. Işik +2
The amplitude and morphology of light curves of solar-like stars change substantially with increasing rotation rate: brightness variations get amplified and become more regular, wh…
