Flows and Non-thermal Velocities in Solar Active Regions Observed with the Extreme-ultraviolet Imaging Spectrometer on Hinode: A Tracer of Active Region Sources of Heliospheric Magnetic Fields?
G. A. Doschek, H. P. Warren, J. T. Mariska +4
From Doppler velocity maps of active regions constructed from spectra obtained by the Extreme-ultraviolet Imaging Spectrometer (EIS) on the Hinode spacecraft we observe large areas…
Observations of Solar Doppler Shift Oscillations with the EUV Imaging Spectrometer on Hinode
John T. Mariska, Harry P. Warren, David R. Williams +1
Damped Doppler shift oscillations have been observed in emission lines from ions formed at flare temperatures with the Solar Ultraviolet Measurements of Emitted Radiation spectrome…
High precision density measurements in the solar corona: I. Analysis methods and results for Fe XII and Fe XIII
P. R. Young, T. Watanabe, H. Hara +1
The EUV Imaging Spectrometer (EIS) instrument on board the Hinode satellite has access to some of the best coronal density diagnostics and the high sensitivity of the instrument no…
Observation and Modeling of Coronal "Moss" With the EUV Imaging Spectrometer on Hinode
Harry P. Warren, Amy R. Winebarger, John T. Mariska +2
Observations of transition region emission in solar active regions represent a powerful tool for determining the properties of hot coronal loops. In this Letter we present the anal…
Characteristics of Solar Flare Doppler Shift Oscillations Observed with the Bragg Crystal Spectrometer on Yohkoh
John T. Mariska
This paper reports the results of a survey of Doppler shift oscillations measured during solar flares in emission lines of S XV and Ca XIX with the Bragg Crystal Spectrometer (BCS)…
Observations of Solar Flare Doppler Shift Oscillations with the Bragg Crystal Spectrometer on Yohkoh
John T. Mariska
Oscillations in solar coronal loops appear to be a common phenomenon. Transverse and longitudinal oscillations have been observed with both the Transition Region and Coronal Explor…
