We will discuss the role of near surface flows, based on
observations.

The existence of starspots on cool main-sequence stars other
than the Sun is known from observations. However, the
properties of these spots (their sizes, temperature,
magnetic field strength, etc.) are not well constrained. We
aim at determining some of these properties in two- and
three-dimensional radiative MHD simulations of the
near-surface layers in a local-box setup. In a...

Models of sunspot spectra based on Sumer observations are
used to calculate line profiles observed by IRIS at various
disk positions. The models are used to calculate net
radiative cooling rates, which indicate the required heating
as a function of height.
