On the extent of the moat flow in axisymmetric sunspots
M. Verma, P. Kummerow, C. Denker
Unipolar, axisymmetric sunspots are figuratively called "theoretician's sunspots" because their simplicity supposedly makes them more suitable for theoretical descriptions or numer…

Horizontal flow fields in and around a small active region-- The transition period between flux emergence and decay
M. Verma, C. Denker, H. Balthasar +28
Aims. Combining high-resolution and synoptic observations aims to provide a comprehensive description of flux emergence at photospheric level and of the growth process that eventua…

Flows in and around active region NOAA12118 observed with the GREGOR solar telescope and SDO/HMI
M. Verma, C. Denker, H. Balthasar +28
Accurate measurements of magnetic and velocity fields in and around solar active regions are key to unlocking the mysteries of the formation and the decay of sunspots. High spatial…
