Subsurface helicity of active regions 12192 and 10486

Author: Rudolf Komm
The active region 10486 that produced the Halloween flares in 2003 initiated our interest in the kinetic helicity of subsurface flows associated with active regions. This lead to the realization that the helicity of subsurface fl ... more

Chromospheric heating by magneto-acoustic waves - a science case for EST

Author: Michal Sobotka
An EST science case concerning the possible heating of solar chromosphere by magneto-acoustic waves is elaborated. The case is based on observations of intensity, polarisation, and Doppler velocity of selected spectral lines with ... more

Continuum intensity - magnetic field relation in sunspots

Author: Michal Sobotka
We present high-resolution full-Stokes measurements of sunspots, using the highly-sensitive full-split (g=3) infrared line Fe I 1564.85 nm, and compare them with simultaneous continuum intensity measurements. We extend the classic ... more
