A new Method to Constrain the Iron Abundance from Cooling Delays in Coronal Loops
Markus J. Aschwanden, C. J. Schrijver, A. R. Winebarger +1
Recent observations with TRACE reveal that the time delay between the appearance of a cooling loop in different EUV temperature filters is proportional to the loop length, dt_12 ~…
Review of Coronal Oscillations - An Observer's View
Markus J. Aschwanden
Recent observations show a variety of oscillation modes in the corona. Early non-imaging observations in radio wavelengths showed a number of fast-period oscillations in the order…
Tomographic 3D-Modeling of the Solar Corona with FASR
Markus J. Aschwanden, David Alexander, Marc DeRosa
The "Frequency-Agile Solar Radiotelescope" (FASR) litteraly opens up a new dimension in addition to the 3D Euclidian geometry: the frequency dimension. The 3D geometry is degenerat…
On the Photometric Accuracy of RHESSI Imaging and Spectrosocopy
Markus J. Aschwanden, Thomas R. Metcalf, Sam Krucker +4
We compare the photometric accuracy of spectra and images in flares observed with the Ramaty High Energy Solar Spectroscopic Imager (RHESSI)}spacecraft. We test the accuracy of the…
MHD Sausage Mode Oscillations in Coronal Loops
Markus J. Aschwanden, Valery M. Nakariakov, Victor F. Melnikov
A recent study by Nakariakov et al. pointed out that the dispersion relation of MHD sausage mode oscillations has been incorrectly applied to coronal loops, neglecting the highly d…
Observational Tests of Damping by Resonant Absorption in Coronal Loop Oscillations
Markus J. Aschwanden, Richard W. Nightingale, Jesse Andries +2
One of the proposed damping mechanisms of coronal (transverse) loop oscillations in the kink-mode is resonant absorption as a result of the Alfven speed variation at the outer boun…
