GAM4 . 9 Comets
Konrad Schwingenschuh, Space Research Institute,
Austrian Academy of Sciences, Inffeldgasse 12, A-8010
Graz, AUSTRIA.
Tatsuki Ogino
A P Remizov
The main objective will be to discuss new results about the
solar wind interaction with ·comets, cometary dust and neutral
gas environments, and comparisons between comets and other
outgassing solar system bodies. Papers will describe
investigations using the results of in situ or Earth-based
observations, computer simulations or theoretical conclusions.
GAM4 .10 The Interplanetary Magnetic Field: Observations and
Models
I S Veselovsky, Institute of Nuclear Physics, Moscow
State University, Moscow 119899, USSR.
N U Crooker
T Saito
The following topics will be covered: 3D time-dependent and
averaged IMF; Heliospheric current sheet structure; Largescale
magnetic fields. Observational and theoretical papers
will be welcome.
GAM4. 11 From the Bow Shock to the Magnetopause: the
Magnetos heath
David G Sibeck, Applied Physics Laboratory, The Johns
Hopkins University, Johns Hopkins Road, Laurel MD
20707-6099, USA.
Mark A Saunders
Stephen A Fuselier
Oleg L Vaisberg
Consideration will be given to case studies and statistical
observational studies of transient events and the steady state
magnetosheath structure in the context of new and existing
magnetosheath models. Bow shock and magnetopause studies with
emphasis upon t he magnetosheath are also invited.
GAM4.12 The Microphysics of Shocks and Other Discontinuities
Michelle F Thomsen, Los Alamos National Laboratory,
Mail Stop D438, Los Alamos NM 87545, USA.
Steven J Schwartz
V G Es e levich
Stephen H Brecht
Transitions in plasmas are in r ealit y ne ve r discontinuous but
occ ur t hrough finite spatial scalele ngths. Properties like
transport and dissipation depe nd crucia lly upon the
microphysics of the transition . Rece nt research on the shocks,
tange ntial discontinuities, contact discontinuities etc. will
be t he focus of this symposium.
