A major topic of interest is the radial evolution of solar wind
structures. Observations over the past 30 years have shown that as the
plasma moves out from the Sun, the various structures in the magnetic
field and plasma configuration evolve with increasing radial distance.
I now have a project under way in collaboration with Mel Goldstein and
Aaron Roberts at Goddard Space Flight Center on Corotating Interaction
Regions (CIR's) and Coronal Mass Ejections (CME's) under BSF support. In
recent years ,
significant
attention has been given to these resolved structures, which propagate out from
the Sun and generate major interplanetary and magnetospheric effects. The main
focus of this research will be to study the effects of such structures, to find
them in the interplanetary plasma and magnetic field data, and to simulate
their evolution and interaction with the ambient medium and planetary
magnetospheres.
