The energetic atmosphere of the Sun
Sven Wedemeyer, Mats Kirkaune, Miroslav Barta +16
Understanding the mechanisms that heat the Sun's chromosphere and corona to temperatures far exceeding those of the solar photosphere below remains one of the central challenges in…
Solar spicule population properties inferred from IRIS Mg II k off-limb spectra using likelihood-free Bayesian inference
Jiri Stepan, Stanislav Gunar, Akiko Tei +1
Solar spicules are ubiquitous and strongly overlap in off-limb observations, which complicates the interpretation of individual events. We aim to infer population-level properties…
The ASPIICS solar coronagraph aboard the Proba-3 formation flying mission. Scientific objectives and instrument design
A. N. Zhukov, C. Thizy, D. Galano +67
We describe the scientific objectives and instrument design of the ASPIICS coronagraph launched aboard the Proba-3 mission of the European Space Agency (ESA) on 5 December 2024. Pr…
Comparison of Coronal Hole and Quiet Sun Chromosphere Using IRIS Mg II h & k Observations of Polar Off-limb Regions
Akiko Tei, Stanislav Gunar, Takenori J. Okamoto
Solar quiet regions are divided into coronal hole regions (CH) and quiet-Sun regions (QS). The global magnetic field in CH is considered open to interplanetary space, while that in…
The diversity of spectral shapes of hydrogen Lyman lines and Mg II lines in a quiescent prominence
P. Schwartz, S. Gunar, J. Koza +1
Broad sets of spectroscopic observations comprising multiple lines represent an excellent opportunity for diagnostics of the properties of the prominence plasma and the dynamics of…
Prospects and challenges of numerical modelling of the Sun at millimetre wavelengths
Sven Wedemeyer, Gregory Fleishman, Jaime de la Cruz Rodriguez +6
The Atacama Large Millimeter/submillimeter Array (ALMA) offers new diagnostic possibilities that complement other commonly used diagnostics for the study of our Sun. In particular,…
The European Solar Telescope
C. Quintero Noda, R. Schlichenmaier, L. R. Bellot Rubio +14
The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design…
Subarcsecond imaging of a solar active region filament with ALMA and IRIS
J. M. da Silva Santos, S. M. White, K. Reardon +4
Quiescent filaments appear as absorption features on the solar disk when observed in chromospheric lines and at continuum wavelengths in the millimeter (mm) range. Active region (A…
Quiet-Sun hydrogen Lyman-alpha line profile derived from SOHO/SUMER solar-disk observations
S. Gunar, P. Schwartz, J. Koza +1
The solar radiation in the Lyman-alpha spectral line of hydrogen plays a significant role in the illumination of chromospheric and coronal structures, such as prominences, spicules…
IRIS Mg II Observations and Non-LTE Modeling of Off-limb Spicules in a Solar Polar Coronal Hole
Akiko Tei, Stanislav Gunar, Petr Heinzel +4
We investigated the off-limb spicules observed in the Mg II h and k lines by IRIS in a solar polar coronal hole. We analyzed the large dataset of obtained spectra to extract quanti…
2D non-LTE modelling of a filament observed in the H_alpha line with the DST/IBIS spectropolarimeter
P. Schwartz, S. Gunar, J. M. Jenkins +3
We study a fragment of a large quiescent filament observed on May 29, 2017 by the Interferometric BIdimensional Spectropolarimeter (IBIS) mounted at the Dunn Solar Telescope. We fo…
Statistical analysis of UV spectra of a quiescent prominence observed by IRIS
S. Jejčič, P. Schwartz, P. Heinzel +2
The paper analyzes the structure and dynamics of a quiescent prominence that occurred on October 22, 2013. We aim to determine the physical characteristics of the observed prominen…
Visibility of Prominences using the HeI D3 Line Filter on PROBA-3/ASPIICS Coronagraph
S. Jejčič, P. Heinzel, N. Labrosse +4
We determine an optimal width and shape of the narrow-band filter centered around the He\,{\sc i} D line for prominence and coronal mass ejection (CME) observations with the…
ALMA Observations of the Sun in Cycle 4 and Beyond

This document was created by the Solar Simulations for the Atacama Large Millimeter Observatory Network (SSALMON) in preparation of the first regular observations of the Sun with t…
Solar science with the Atacama Large Millimeter/submillimeter Array - A new view of our Sun
S. Wedemeyer, T. Bastian, R. Brajsa +35
The Atacama Large Millimeter/submillimeter Array (ALMA) is a new powerful tool for observing the Sun at high spatial, temporal, and spectral resolution. These capabilities can addr…
SSALMON - The Solar Simulations for the Atacama Large Millimeter Observatory Network
S. Wedemeyer, T. Bastian, R. Brajsa +27
The Solar Simulations for the Atacama Large Millimeter Observatory Network (SSALMON) was initiated in 2014 in connection with two ALMA development studies. The Atacama Large Millim…
