Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Solar and stellar observations
Sven Wedemeyer, Miroslav Barta, Roman Brajsa +35
Observations at (sub-)millimeter wavelengths offer a complementary perspective on our Sun and other stars, offering significant insights into both the thermal and magnetic composit…
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…
AtLAST Science Overview Report
Mark Booth, Pamela Klaassen, Claudia Cicone +81
Submillimeter and millimeter wavelengths provide a unique view of the Universe, from the gas and dust that fills and surrounds galaxies to the chromosphere of our own Sun. Current…
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…
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,…
