The Unresolved Fine Structure Resolved - IRIS observations of the Solar Transition Region
V. Hansteen, B. De Pontieu, M. Carlsson +18
The heating of the outer solar atmospheric layers, i.e., the transition region and corona, to high temperatures is a long standing problem in solar (and stellar) physics. Solutions…
On the prevalence of small-scale twist in the solar chromosphere and transition region
B. De Pontieu, L. Rouppe van der Voort, S. W. McIntosh +21
The solar chromosphere and transition region (TR) form an interface between the Sun's surface and its hot outer atmosphere. Here most of the non-thermal energy that powers the sola…
Hot Explosions in the Cool Atmosphere of the Sun
H. Peter, H. Tian, W. Curdt +20
The solar atmosphere was traditionally represented with a simple one-dimensional model. Over the past few decades, this paradigm shifted for the chromosphere and corona that consti…
Prevalence of Small-scale Jets from the Networks of the Solar Transition Region and Chromosphere
H. Tian, E. E. DeLuca, S. R. Cranmer +24
As the interface between the Sun's photosphere and corona, the chromosphere and transition region play a key role in the formation and acceleration of the solar wind. Observations…
Molecular absorption in transition region spectral lines
Donald Schmit, Davina Innes, Thomas Ayres +3
Aims: We present observations from the Interface Region Imaging Spectrograph (IRIS) of absorption features from a multitude of cool atomic and molecular lines within the profiles o…
The 2014 March 29 X-flare: sub-arcsecond resolution observations of Fe XXI 1354.1
Peter Young, Hui Tian, Sarah Jaeggli
The Interface Region Imaging Spectrometer (IRIS) is the first solar instrument to observe MK plasma at subarcsecond spatial resolution through imaging spectroscopy of the…
