Estimating the Chromospheric Absorption of Transition Region Moss Emission
Bart De Pontieu, Viggo H. Hansteen, Scott W. McIntosh +1
Many models for coronal loops have difficulty explaining the observed EUV brightness of the transition region, which is often significantly less than theoretical models predict. Th…
Observing the Roots of Solar Coronal Heating - in the Chromosphere
Bart De Pontieu, Scott W. McIntosh, Viggo H. Hansteen +1
The Sun's corona is millions of degrees hotter than its 5,000 K photosphere. This heating enigma is typically addressed by invoking the deposition at coronal heights of non-thermal…
Search for high velocities in the disk counterpart of type II spicules
Ø. Langangen, B. De Pontieu, M. Carlsson +3
Recently, De Pontieu et al. (2007b) discovered a class of spicules that evolves more rapidly than previously known spicules, with rapid apparent motions of 50--150 km s, t…
Reappraising Transition Region Line Widths in light of Recent Alfvén Wave Discoveries
Scott W. McIntosh, Bart De Pontieu, Theodore D. Tarbell
We provide a new interpretation of ultraviolet transition region emission line widths observed by the SUMER instrument on the Solar and Heliospheric Observatory (SOHO). This invest…
Spectroscopic measurements of dynamic fibrils in the Ca {\small{II}} 8662 Å line
Oystein Langangen, Mats Carlsson, Luc Rouppe van der Voort +2
We present high spatial resolution spectroscopic measurements of dynamic fibrils (DFs) in the Ca {\small{II}} 8662 Å line. These data show clear Doppler shifts in the identified DF…
