The Spectroscopic Signature of Quasi-periodic Upflows in Active Region Timeseries
Hui Tian, Scott W. McIntosh, Bart De Pontieu
Quasi-periodic propagating disturbances are frequently observed in coronal intensity image sequences. These disturbances have historically been interpreted as being the signature o…
The Spectroscopic Footprint of the Fast Solar Wind
Scott W. McIntosh, Robert J. Leamon, Bart De Pontieu
We analyze a large, complex equatorial coronal hole (ECH) and its immediate surroundings with a focus on the roots of the fast solar wind. We start by demonstrating that our ECH is…
Quasi-periodic Propagating Signals in the Solar Corona: The Signature of Magnetoacoustic Waves or High-Velocity Upflows?
Bart De Pontieu, Scott W. McIntosh
Since the discovery of quasi-periodic propagating oscillations with periods of order three to ten minutes in coronal loops with TRACE and EIT (later with EUVI and EIS), they have b…
On red shifs in the transition region and corona
Viggo H. Hansteen, Hirohisa Hara, Bart de Pontieu +1
We present evidence that transition region red-shifts are naturally produced in episodically heated models where the average volumetric heating scale height lies between that of th…
STEREO Observations of Quasi-Periodically Driven High Velocity Outflows in Polar Plumes
Scott W. McIntosh, Davina E. Innes, Bart De Pontieu +1
Plumes are one of the most ubiquitous features seen at the limb in polar coronal holes and are considered to be a source of high density plasma streams to the fast solar wind. We a…
The Impact of New EUV Diagnostics on CME-Related Kinematics
S. W. McIntosh, B. De Pontieu, R. J. Leamon
We present the application of novel diagnostics to the spectroscopic observation of a Coronal Mass Ejection (CME) on disk by the Extreme Ultraviolet Imaging Spectrometer (EIS) on t…
