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…
An Interface Region Imaging Spectrograph first view on Solar Spicules
T. M. D. Pereira, B. De Pontieu, M. Carlsson +17
Solar spicules have eluded modelers and observers for decades. Since the discovery of the more energetic type II, spicules have become a heated topic but their contribution to the…
Detection of supersonic downflows and associated heating events in the transition region above sunspots
L. Kleint, P. Antolin, H. Tian +18
IRIS data allow us to study the solar transition region (TR) with an unprecedented spatial resolution of 0.33 arcsec. On 2013 August 30, we observed bursts of high Doppler shifts s…
