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…

The role of the Lorentz force in sunspot equilibrium

J. M. Borrero, A. Pastor Yabar, M. Schmassmann +3

Sunspots survive on the solar surface for time-scales ranging from days to months. This requires them to be in an equilibrium involving magnetic fields and hydrodynamic forces. Unf…

Fine-scale opposite-polarity magnetic fields in a solar plage revealed by integral field spectropolarimetry

G. Liu, I. Milić, J. S. Castellanos Duran +3

Plages are small concentrations of strong, nearly vertical magnetic fields in the solar photosphere that expand with height. A high spatial and spectral resolution that can resolve…

Influence of NLTE effects in Fe I lines on inverted atmosphere II. 6301 A and 6302 A lines formed in 3DNLTE

H. N. Smitha, R. Holzreuter, M. van Noort +1

This paper forms the second part of our study on how the neglect of NLTE conditions in the formation of Fe I 6301.5 A and the 6302.5 A lines influences the atmosphere obtained by i…

Detection of the strongest magnetic field in a sunspot light bridge

J. S. Castellanos Durán, A. Lagg, S. K. Solanki +1

Traditionally, the strongest magnetic fields on the Sun have been measured in sunspot umbrae. More recently, however, much stronger fields have been measured at the ends of penumbr…

The influence of NLTE effects in Fe I lines on an inverted atmosphere I. 6301 A and 6302 A lines formed in 1D NLTE

H. N. Smitha, R. Holzreuter, M. van Noort +1

Ultraviolet over-ionisation of iron atoms in the solar atmosphere leads to deviations in their level populations from the Saha-Boltzmann statistics. This causes their line profiles…
