Quantitative Measurements of CME-driven Shocks from LASCO Observations
Veronica Ontiveros, Angelos Vourlidas
In this paper, we demonstrate that CME-driven shocks can be detected in white light coronagraph images and in which properties such as the density compression ratio and shock direc…
Driving Currents for Flux Rope Coronal Mass Ejections
Prasad Subramanian, Angelos Vourlidas
We present a method for measuring electrical currents enclosed by flux rope structures that are ejected within solar coronal mass ejections (CMEs). Such currents are responsible fo…
The Brightness of Density Structures at Large Solar Elongation Angles: What is Being Observed by STEREO/SECCHI?
N. Lugaz, A. Vourlidas, I. I. Roussev +3
We discuss features of coronal mass ejections (CMEs) that are specific to heliospheric observations at large elongation angles. Our analysis is focused on a series of two eruptions…
POLAR Investigation of the Sun - POLARIS
T. Appourchaux, P. Liewer, M. Watt +34
The POLAR Investigation of the Sun (POLARIS) mission uses a combination of a gravity assist and solar sail propulsion to place a spacecraft in a 0.48 AU circular orbit around the S…
Three-Dimensional MHD Simulation of the 2003 October 28 Coronal Mass Ejection: Comparison with LASCO Coronagraph Observations
Ward Manchester, Angelos Vourlidas, Gabor Toth +6
We numerically model the coronal mass ejection (CME) event of October 28, 2003 that erupted from active region 10486 and propagated to Earth in less than 20 hours causing severe ge…
STEREO/SECCHI Stereoscopic Observations Constraining the Initiation of Polar Coronal Jets
S. Patsourakos, E. Pariat, A. Vourlidas +2
We report on the first stereoscopic observations of polar coronal jets made by the EUVI/SECCHI imagers on board the twin STEREO spacecraft. The significantly separated viewpoints (…
