Thermodynamic and magnetic evolution of an eruptive C-class solar flare observed with SST/TRIPPEL-SP

C. J. Díaz Baso, J. de la Cruz Rodríguez, H. -P. Doerr +4

Solar flares are complex phenomena driven by the release of magnetic energy, but a large energy reservoir is not sufficient to determine their eruptive potential; the magnetic topo…

Inference of magnetic fields in the very quiet Sun

M. J. Mart\' inez González, A. Pastor Yabar, A. Lagg +29

We present high-precision spectro-polarimetric data with high spatial resolution (0.4) of the very quiet Sun at 1.56m obtained with the GREGOR telescope to shed some light o…

Absolute velocity measurements in sunspot umbrae

J. Löhner-Böttcher, W. Schmidt, R. Schlichenmaier +3

In sunspot umbrae, convection is largely suppressed by the strong magnetic field. Previous measurements reported on negligible convective flows in umbral cores. Based on this, nume…

Verification of the helioseismic Fourier-Legendre analysis for meridional flow measurements

Markus Roth, Hans-Peter Doerr, Thomas Hartlep

Measuring the Sun's internal meridional flow is one of the key issues of helioseismology. Using the Fourier-Legendre analysis is a technique for addressing this problem. We validat…
