IDIV01 Solar-terrestrial connections: International
Living With a Star (Divisions IV and III)
International Living With a Star (ILWS) is the primary vehicle
by which the space agencies and equivalent space authorities in
nearly 30 countries coordinate activities and projects on Solar-Terrestrial
Science. ILWS has a broad scientific coverage encompassing all current
research interests, from solar dynamo theory to potential climatic
effects of solar variability. In between, classical space plasma
problems such as collisionless shocks, magnetic reconnection, substorms,
particle acceleration, auroral physics, and magnetosphere-ionosphere-thermosphere
coupling make for an exceedingly rich and intrinsically multidisciplinary
program. This session will feature presentations by leading scientists
from ILWS member countries on how to tackle outstanding problems
in Sun-Earth Connection, utilizing modern experimental and theoretical
techniques and extant synergy in the international community.

GAIV01 The Sun: Its interior, atmosphere and wind
Continuous ground- and space-based observations of the Sun have
provided detailed information on the solar interior, extended corona
and solar wind. These observations offer a unique capability to
investigate the physical processes responsible for the dynamic nature
of the Sun. The combination of these observations with realistic
modeling is reshaping our understanding of the solar magnetic field
and solar activity, and the mechanisms by which the corona is heated
and the solar wind is accelerated. The symposium invites contributions
covering observations, theory and modeling of the different aspects
of the Sun, including its interior, dynamo, magnetic field, atmosphere,
and wind. This broad scope is aimed at stimulating exchange and
promoting discussion on physically connected phenomena which are
seldom discussed in a single meeting.

GAIV02 Physics of the interplanetary medium: From micro- to
mesoscales
The interplanetary medium is characterized by a multiplicity
of scales, ranging from short-scale, high-frequency fluctuations
to low-frequency MHD scales to solar rotation and solar cycle scales.
These scales interact in a variety of ways such as, for example,
cosmic ray modulation, which results from scattering by low-frequency
turbulence, and is strongly mediated by the solar cycle. Other examples
are the interaction of the solar wind with the local interstellar
medium, the acceleration and transport of energetic particles such
as solar energetic particles, the evolution and dynamics of turbulence
in the interplanetary medium, emission processes, the characteristics
of collisionless shock waves, etc. This session solicits contributions
that explore the coupling of multiple scales and physical processes
in the context of the interplanetary medium.

GAIV03 Foreshock, shock, and magnetosheath physics for collisionless
shocks
The session invites contributions of observational and theoretical
studies of the basic physical mechanisms of the energy transfer
through collisionless shocks, characteristic temporal and spatial
scales of the shock front structure, role of the fine spatial structure
in the shock thermalization process, generation of waves and their
role, as well as the particle acceleration process in the vicinity
of the bow shock and interplanetary shocks. Recently, direct in
situ measurements of high frequency wave fields in the electron
foreshock region allowed to better understand the nature of wave
activity observed. Multi-satellite measurements in the magnetosheath
combined with new techniques of data analysis provides new impetus
to the identification of wave characteristics and their role in
ion thermalization process. These and other similar topics, are
the primary objectives of this session, namely, to put together
recent "in situ" measurements from different space projects
with theoretical work and models.

GAIV04 Interaction of fast flowing plasmas with the neutral
environments of unmagnetized bodies
This session will summarize recent progress in the space plasma
physics of solar system bodies without measurable dynamo magnetic
field, including new results from Mars Global Surveyor and Mars
Express at Mars and from Cassini around Saturn's moon Titan. The
interaction of Mars with the solar wind is mainly of the atmospheric
type like Venus with strong modifications of the local ionospheric
structure by the crustal fields, and their exosphere makes these
planets also share common physical processes with comets. The interaction
of Titan with the fast co-rotating plasma inside the magnetosphere
of Saturn is another example of such interaction. Numerous open
issues include upstream waves, plasma boundaries and their dynamics,
atmospheric and ionospheric escapes, etc. Recent results in data
analysis and theoretical results, including numerical simulations
are encouraged. Papers related to forthcoming space missions (Venus-Express
and Rosetta) are also welcome.

GAIV05 International Heliophysical Year: A program of global
research
In 1957 a program of international research was organized as
the International Geophysical Year (IGY) to study global phenomena
of the Earth and geospace. The IGY involved about 60,000 scientists
from 66 nations, working at thousands of stations, from pole to
pole to obtain simultaneous, global observations on Earth and in
space. There had never been anything like it before. The fiftieth
anniversary of the International Geophysical Year will occur in
2007. We propose to organize an international program of scientific
collaboration for this time period called the International Heliophysical
Year (IHY). Like its predecessors, the IHY will focus on fundamental
global questions of Earth science via the following goals: 1) Obtain
a coordinated set of observations to study at the largest scale
the solar-generated events and their effect life and climate on
Earth, 2) Document and report the observations and provide a forum
for the development of new scientific results utilizing these observations,
3) Foster international cooperation in the study of Heliophysical
phenomena now and in the future, and 4) Communicate the unique scientific
results of the IHY to the interested scientific community and to
all the peoples of Earth.
The objective of the IHY is to discover the physical mechanisms
at work which couple the Earth to events from the Sun and heliosphere.
The systematic global study of this connection is to be the central
theme of the IHY. This special session will focus on research and
campaign efforts which lay the groundwork for the IHY. This session
will be used as a forum for discussion of the nature of the IHY,
and to solicit suggestions and ideas from the community.

GAIV06 Reporter Reviews
This session contains reviews of recent advances, both theoretical
and observational, on the Sun, solar wind, and heliosphere. Given
by active researchers, these reviews will cover a comprehensive
range of topics in a manner that is accessible to researchers from
other IAGA Divisions, while offering synthesis and context to Division
IV scientists. All talks in this session are by invitation only.
