| Summary:
We compute realistic 3D radiative MHD near-surface models of starspots with
substantial penumbrae on cool main-sequence stars using the MURaM simulation
code. This work is an improvement on the the previous starspot models in a slab
geometry. The umbra, penumbra and the quiet star for all starspots are
distinct, not only in intensity and temperature, but also in thermodynamic and
velocity structure. These models represent a significant step towards modelling
contribution of starspots to stellar lightcurves.
