The first out-of-ecliptic observations of the polar magnetic field of the Sun

D. Calchetti, S. K. Solanki, J. Hirzberger +25

Direct remote-sensing observations of the solar poles have been hindered by the restricted view obtained from the ecliptic plane. For the first time ever, Solar Orbiter with its re…

Formation of chromospheric Fe I lines in the near ultraviolet in 1D atmospheres

E. Harnes, H. N. Smitha, A. Korpi-Lagg +2

In the near ultraviolet (NUV) part of the solar spectrum, there are several Fe I lines with very broad profiles, typical of chromospheric lines. These lines are largely unexplored…

Magnetic properties of orphan penumbrae

J. S. Castellanos Durán, B. Löptien, A. Korpi-Lagg +2

Orphan penumbrae (OPU) are features resembling sunspot penumbrae, but are not connected to an umbra. Here we compare OPUs and sunspot penumbrae, including their filaments. We also…

Superstrong magnetic fields in sunspot bipolar light bridges

J. S. Castellanos Durán, A. Korpi-Lagg, S. K. Solanki +2

Recent solar observations of bipolar light bridges (BLBs) in sunspots have, in a few individual cases, revealed magnetic fields up to 8.2 kG, which is at least twice as strong as t…
