ABSTRACT A three-dimensional magnetohydrodynamic (MHD) model for the propagation
and dissipation of Alfvén waves in a coronal loop is developed. The model includes the …

The detection of Earth-like planets with the radial-velocity (RV) method is currently limited by
the presence of stellar activity signatures. On rotational time-scales, spots and plages (or …

Abstract The Daniel K. Inouye Solar Telescope (DKIST) Visible Spectro-Polarimeter (ViSP)
is a traditional slit-scanning spectrograph with the ability to observe solar regions up to a …

The Mg ii h&k lines are the prime chromospheric diagnostics of NASA's Interface Region
Imaging Spectrograph (IRIS). In the previous papers of this series, we used a realistic three …

We consider recent observations of the chromospheric network and argue that the bright
network grains observed in the Ca II H and K lines are heated by an as-yet-unidentified …

Context. The wings of the Ca ii H and K lines provide excellent photospheric temperature
diagnostics. At the Swedish 1-m Solar Telescope (SST), the blue wing of Ca ii H is scanned …

We use sequences of images and magnetograms from Hinode to study magnetic elements
in internetwork parts of the quiet solar photosphere. Visual inspection shows the existence of …

High-resolution solar images taken in the blue wing of the Balmer H α line with the Dutch
Open Telescope show intergranular magnetic elements as strikingly bright features, similar …

Aims. We investigate wave propagation and energy transport in magnetic elements, which
are representatives of small scale magnetic flux concentrations in the magnetic network on …

We compare high-quality image sequences from the Dutch Open Telescope (DOT) with
synthetic image sequences obtained from 3D radiation-hydrodynamics simulations of the …
