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…
Evidence of Non-Thermal Particles in Coronal Loops Heated Impulsively by Nanoflares
Paola Testa, Bart De Pontieu, Joel Allred +21
The physical processes causing energy exchange between the Sun's hot corona and its cool lower atmosphere remain poorly understood. The chromosphere and transition region (TR) form…
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…
High-resolution Observations of the Shock Wave Behavior for Sunspot Oscillations with the Interface Region Imaging Spectrograph
H. Tian, E. DeLuca, K. K. Reeves +20
We present the first results of sunspot oscillations from observations by the Interface Region Imaging Spectrograph. The strongly nonlinear oscillation is identified in both the sl…
The Interface Region Imaging Spectrograph (IRIS)
B. De Pontieu, A. M. Title, J. Lemen +85
The Interface Region Imaging Spectrograph (IRIS) small explorer spacecraft provides simultaneous spectra and images of the photosphere, chromosphere, transition region, and corona…
