Diagnostic capabilities of spectropolarimetric observations for understanding solar phenomena I. Zeeman-sensitive photospheric lines
C. Quintero Noda, P. S. Barklem, R. Gafeira +7
Future ground-based telescopes will expand our capabilities for simultaneous multi-line polarimetric observations in a wide range of wavelengths, from the near-ultraviolet to the n…
3D solar coronal loop reconstructions with machine learning
Iulia Chifu, Ricardo Gafeira
The magnetic field plays an essential role in the initiation and evolution of different solar phenomena in the corona. The structure and evolution of the 3D coronal magnetic field…
Temporal evolution of short-lived penumbral microjets
A. Siu-Tapia, L. R. Bellot Rubio, D. Orozco Suárez +1
Context. Penumbral microjets are elongated jet-like brightenings observed in the chromosphere above sunspot penumbrae. They are transient events that last from a few seconds to sev…
Analysis of full disc Ca II K spectroheliograms III. Plage area composite series covering 1892-2019
Theodosios Chatzistergos, Ilaria Ermolli, Natalie A. Krivova +16
We derive the plage area evolution over the last 12 solar cycles employing data from all Ca II K archives available publicly in digital form known to us, including several as yet u…
