The Evolution of Ion Charge States in Coronal Mass Ejections
J. Martin Laming, Elena Provornikova, Yuan-Kuen Ko
We model the observed charge states of the elements C, O, Mg, Si, and Fe in the coronal mass ejections (CMEs) ejecta. We concentrate on "halo" CMEs observed in situ by ACE/SWICS to…
Observations of Slow Solar Wind from Equatorial Coronal Holes
Y. -M. Wang, Y. -K. Ko
Because of its distinctive compositional properties and variability, low-speed ( km s) solar wind is widely believed to originate from coronal streamers, unlik…
Element Abundances: A New Diagnostic for the Solar Wind
J. Martin Laming, Angelos Vourlidas, Clarence Korendyke +11
We examine the different element abundances exhibited by the closed loop solar corona and the slow speed solar wind. Both are subject to the First Ionization Potential (FIP) Effect…
On the Remote Detection of Suprathermal Ions in the Solar Corona and their Role as Seeds for Solar Energetic Particle Production
J. Martin Laming, J. Dan Moses, Yuan-Kuen Ko +3
Forecasting large Solar Energetic Particle (SEP) events associated with shocks driven by fast coronal mass ejections (CME) pose a major difficulty in the field of Space Weather. Be…
Transition Region Emission from Solar Flares during the Impulsive Phase
H. Johnson, J. C. Raymond, N. A. Murphy +4
There are relatively few observations of UV emission during the impulsive phases of solar flares, so the nature of that emission is poorly known. Photons produced by solar flares c…
Science Objectives for an X-Ray Microcalorimeter Observing the Sun
J. Martin Laming, J. Adams, D. Alexander +57
We present the science case for a broadband X-ray imager with high-resolution spectroscopy, including simulations of X-ray spectral diagnostics of both active regions and solar fla…
