Observations of Active Region Loops with the EUV Imaging Spectrometer on Hinode

Harry P. Warren, Ignacio Ugarte-Urra, George A. Doschek +2

Previous solar observations have shown that coronal loops near 1 MK are difficult to reconcile with simple heating models. These loops have lifetimes that are long relative to a ra…

Observations of Transient Active Region Heating with Hinode

Harry P. Warren, Ignacio Ugarte-Urra, David H. Brooks +3

We present observations of transient active region heating events observed with the Extreme Ultraviolet Imaging Spectrometer (EIS) and X-ray Telescope (XRT) on Hinode. This initial…

Hinode EUV Imaging Spectrometer Observations of Solar Active Region Dynamics

John T. Mariska, Harry P. Warren, Ignacio Ugarte-Urra +3

The EUV Imaging Spectrometer (EIS) on the Hinode satellite is capable of measuring emission line center positions for Gaussian line profiles to a fraction of a spectral pixel, resu…

The X10 Flare on 2003 October 29: Triggered by Magnetic Reconnection between Counter-Helical Fluxes?

Y. Liu

Vector magnetograms taken at Huairou Solar Observing Station (HSOS) and Mees Solar Observatory (MSO) reveal that the super active region (AR) NOAA 10486 was a complex region contai…

Ionisation state, excited populations and emission of impurities in dynamic finite density plasmas. I: The generalised collisional-radiative model for light elements

H. P. Summers, W. J. Dickson, M. G. O'Mullane +6

The paper presents an integrated view of the population structure and its role in establishing the ionisation state of light elements in dynamic, finite density, laboratory and ast…
