  • Title: CME propagation and expansion in 3-D space in the heliosphere based on STEREO/SECCHI observations.
  • Abstract: We report a study of kinematics and morphological evolution of CMEs by using STEREO/SECCHI observation to track in 3-D space a set of well observed events from the sun to a large distance in the heliosphere. The CME tracking is based on the Raytrace model (Thernisien et al 2006), which is able to represent a CME as a 3-D flux rope in the upper portion and two straight legs in the lower portion. The true 3-D location can be obtained. We are able to further calculate 3D velocity and 3D acceleration of CMEs free of project effect. In particular, the true cross-section of CMEs, and thus the expansion speed can be found. For the 5 events studied, we find that their bulk velocities eventually converge into a narrow range of 190 km/s – 430 km/s, while their initial velocities range from about 150 km/s to 1500 km/s. Their expansion velocities also converge into a narrow range between 140 km/s and 300 km/s. We find that the deceleration for fast events and acceleration for slow events mainly occur within 40 solar radii.

There are two Journal Clubs this semester: A Joint Space Weather Journal Club and the Astrophysics Journal Club and a stand-alone Space Weather Journal Club. The joint journal club meets every other week (generally in SUB II). See http://physics.gmu.edu/~mjordan/AJC.htmlfor links to papers. The stand-along club meets intermittenly in the off weeks (generally in Res. I, room 301).
