Waves and oscillations have been observed in the Sun's atmosphere for over half a century.
While such phenomena have readily been observed across the entire electromagnetic …

Determining the heating mechanism (or mechanisms) that causes the outer atmosphere of
the Sun, and many other stars, to reach temperatures orders of magnitude higher than their …

Abstract The Interface Region Imaging Spectrograph (IRIS) small explorer spacecraft
provides simultaneous spectra and images of the photosphere, chromosphere, transition …

Alfvén waves, transverse incompressible magnetic oscillations, have been proposed as a
possible mechanism to heat the Sun's corona to millions of degrees by transporting …

We use high-resolution observations of the Sun in Ca II H (3968 Å) from the Solar Optical
Telescope on Hinode to show that there are at least two types of spicules that dominate the …

The chromosphere is a thin layer of the solar atmosphere that bridges the relatively cool
photosphere and the intensely heated transition region and corona. Compressible and …

In this article we review small-scale dynamo processes that are responsible for magnetic
field generation on scales comparable to and smaller than the energy carrying scales of …

Over the last two decades the uninterrupted, high resolution observations of the Sun, from
the excellent range of telescopes aboard many spacecraft complemented with observations …

The Sun, stars similar to it, and many rather dissimilar to it, have chromospheres, regions
classically viewed as lying above the brilliant photosphere and characterized by a positive …

Outwardly propagating intensity disturbances are a common feature in large, quiescent
coronal loop structures. In this paper, an overview is given of the observed properties and …
