Indications of stellar coronal mass ejections through coronal dimmings

Astrid M. Veronig, Petra Odert, Martin Leitzinger +3

Coronal mass ejections (CMEs) are huge expulsions of magnetized matter from the Sun and stars, traversing space with speeds of millions of kilometers per hour. Solar CMEs can cause…

The 2019 International Women's Day event: A two-step solar flare with multiple eruptive signatures and low Earth impact

Dumbovic, M., Veronig +15

We present a detailed analysis of an eruptive event that occurred on early 2019 March 8 in active region AR 12734, to which we refer as the International Women's day event. The eve…

Multi-channel coronal hole detection with convolutional neural networks

R. Jarolim, A. M. Veronig, S. Hofmeister +4

We develop a reliable, fully automatic method for the detection of coronal holes, that provides consistent full-disk segmentation maps over the full solar cycle and can perform in…

Probing the Solar Meridional Circulation using Fourier Legendre Decomposition

D. C. Braun, A. C. Birch, Y. Fan

We apply the helioseismic methodology of Legendre Function Decomposition to 88 months of Dopplergrams obtained by the Helioseismic and Magnetic Imager (HMI) as the basis of inferri…

Inferring solar differential rotation through normal-mode coupling using Bayesian statistics

Samarth G. Kashyap, Srijan Bharati Das, Shravan M. Hanasoge +2

Normal-mode helioseismic data analysis uses observed solar oscillation spectra to infer perturbations in the solar interior due to global and local-scale flows and structural asphe…

On a limitation of Zeeman polarimetry and imperfect instrumentation in representing solar magnetic fields with weaker polarization signal

Alexei A. Pevtsov, Yang Liu, Ilpo Virtanen +4

Full disk vector magnetic fields are used widely for developing better understanding of large-scale structure, morphology, and patterns of the solar magnetic field. The data are al…
