Asymmetric expansion of coronal mass ejections in the low corona
Hebe Cremades, Francisco A. Iglesias, Luciano A. Merenda
Aims. The study of the morphology of coronal mass ejections (CMEs) is an auspicious approach to understanding how magnetic fields are structured within CMEs. Although earlier studi…
Analysis of a long-duration AR throughout five solar rotations: Magnetic properties and ejective events
Francisco A. Iglesias, Hebe Cremades, Luciano A. Merenda +4
Coronal mass ejections (CMEs), which are among the most magnificent solar eruptions, are a major driver of space weather and can thus affect diverse human technologies. Different p…
The Height of Chromospheric Loops in an Emerging Flux Region
L. Merenda, A. Lagg, S. K. Solanki
Context. The chromospheric layer observable with the He I 10830 Å triplet is strongly warped. The analysis of the magnetic morphology of this layer therefore requires a reliable te…
Convective Nature of Sunspot Penumbral Filaments: Discovery of Downflows in the Deep Photosphere
Jayant Joshi, A. Pietarila, J. Hirzberger +3
We study the velocity structure of penumbral filaments in the deep photosphere to obtain direct evidence for the convective nature of sunspot penumbrae. A sunspot was observed at h…
Spectropolarimetry of solar prominences
R. Ramelli, M. Bianda, J. Trujillo Bueno +2
A large set of high precision full-Stokes spectropolarimetric observations of prominences in He-D3, Halpha and Hbeta lines has been recorded with the ZIMPOL polarimeter at the Greg…
The Hanle and Zeeman Effects in Solar Spicules
R. Ramelli, M. Bianda, L. Merenda +1
A large set of high precision full-Stokes spectropolarimetric observations of the He-D3 line in spicules has been recorded with the ZIMPOL polarimeter at the Gregory-Coude Telescop…
