The solar wind-magnetosphere-ionosphere system consists of many relatively
sharp and well-defined boundaries separating large regions of plasma with
different characteristics. These boundaries can have complicated inner
structure and are often associated with strong energy conversion as well
as mass, momentum and energy transfer. The understanding of
all the processes within the boundaries as well as processes forming
the boundaries is a challenging task.
In ST16 session we would like to focus on dynamic features and
substructures of the thin magnetospheric boundaries and adjoined boundary
layers, starting from the bow shock (BS) and magnetopause (MP) and
finishing by plasma sheet boundary layer (PSBL) and plasmapause.
Intermediate boundaries, such as 'slow wave' or 'secondary shock' in
magnetosheath (MSH), would be also addressed.
We solicit here observational (e.g. from Cluster, Double Star, Interball,
Polar, Geotail etc. missions) and theory/simulation works; their comparison
is especially welcome, along with in situ and ground-based data during
magnetic conjunctions.
A few examples of the topics that might be of particular
interest for the ST16 session:
- the intrinsic structure of the boundaries,
- the transport processes within and across the boundaries,
- plasma wave generation within the boundaries,
- the role of finite-amplitude waves and wave-particle interaction in
forming and dynamics of the collisionless boundaries,
- the nonlinear effects near the boundaries,
- narrow current sheets on ion-gyroradius scales, Hall dynamics in the
sheets with and without 'classic' reconnection,
- origin of electron-scale current sheets from: polarization drift, reconnection, turbulent cascades etc.
- boundary deformation by plasma jets and jet formation at the boundaries,
- surface charges and low-magnetic-field regions,
- comparisons of boundaries - stationary vs. unsteady, smooth vs. indented, laminar vs. turbulent, etc.
- plasma-plasma versus magnetic barrier/plasma interactions.
