Description
During the last ten years, our understanding of sunspot fine
structure and heating through convection has improved
dramatically thanks to a combination of numerical MHD
simulations and high-resolution imaging and
spectropolarimetric data. I will summarise some of the
recent observations, with emphasis on data from the Swedish
1-m Solar Telescope (SST), and how these and simple models
led to a fundamental shift in our understanding of the
sunspot penumbra and its Evershed flow.
