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…
The Critical Coronal Transition Region: A Physics-framed Strategy to Uncover the Genesis of the Solar Wind and Solar Eruptions
Angelos Vourlidas, Amir Caspi, Yuan-Kuen Ko +10
Our current theoretical and observational understanding suggests that critical properties of the solar wind and Coronal Mass Ejections (CMEs) are imparted within 10 Rs, particularl…
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…
EUV and X-Ray Observations of Comet Lovejoy (C/2011 W3) in the Lower Corona
Patrick I. McCauley, Steven H. Saar, John C. Raymond +2
We present an analysis of EUV and soft X-ray emission detected toward Comet Lovejoy (C/2011 W3) during its post-perihelion traverse of the solar corona on December 16, 2011. Observ…
