Modelling solar radial velocities and photometric variability with SOAPv4

Alba Barka, Eduardo Cristo, Ângela R. G. Santos +5

Stellar activity remains one of the main limitations in the detection of Earth-like planets using radial velocity (RV) measurements. The Sun, as the only star for which surface fea…

The effect of data-driving and relaxation model on magnetic flux rope evolution and stability

Andreas Wagner, Daniel J. Price, Slava Bourgeois +7

We investigate the effect of data-driving on flux rope eruptivity in magnetic field simulations by analysing fully data-driven modelling results of active region (AR) 12473 and AR1…

The Automatic Identification and Tracking of Coronal Flux Ropes -- Part II: New Mathematical Morphology-based Flux Rope Extraction Method and Deflection Analysis

Andreas Wagner, Slava Bourgeois, Emilia K. J. Kilpua +9

We present a magnetic flux rope (FR) extraction tool for solar coronal magnetic field modelling data, which builds upon the methodology from Wagner et al. (2023). We apply the sche…

Analysis of full-disc H alpha observations: Carrington maps and filament properties in 1909-2022

Theodosios Chatzistergos, Ilaria Ermolli, Dipankar Banerjee +14

Full disc observations of the Sun in the H line provide information about the solar chromosphere and in particular about the filaments, which are dark and elongated features tha…

Magnetic Energy Powers the Corona: How We Can Understand its 3D Storage & Release

Amir Caspi, Daniel B. Seaton, Roberto Casini +12

The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poo…

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…
