The on-ground data reduction and calibration pipeline for SO/PHI-HRT
J. Sinjan, D. Calchetti, J. Hirzberger +47
The ESA/NASA Solar Orbiter space mission has been successfully launched in February 2020. Onboard is the Polarimetric and Helioseismic Imager (SO/PHI), which has two telescopes, a…
On the (in)stability of sunspots
Hanna Strecker, Wolfgang Schmidt, Rolf Schlichenmaier +1
The stability of sunspots is one of the long-standing unsolved puzzles in the field of solar magnetism. We study the effects that destabilise and stabilise the flux tube of a simul…
Convective blueshifts in the solar atmosphere: III. High-accuracy observations of spectral lines in the visible
Johannes Löhner-Böttcher, Wolfgang Schmidt, Rolf Schlichenmaier +2
Convective motions in the solar atmosphere cause spectral lines to become asymmetric and shifted in wavelength. For photospheric lines, this differential Doppler shift varies from…
Convective blueshifts in the solar atmosphere II. High-accuracy observations of the Fe i 6173.3Å line and deviations of full-disk Dopplergrams
Franziska Stief, Johannes Löhner-Böttcher, Wolfgang Schmidt +2
Granular convective motions reach into the lower solar atmosphere, typically causing photospheric spectral lines to exhibit a differential line shift. This Doppler shift to shorter…
