Preliminary Scientific Program Summary:
The identification and recovery of pre-solar grains in meteorites has caused a revolution in stellar structure and nucleosynthesis calculations.  Yet the extent of this revolution is still not as large as it could be, nor are the full implications of the revolution fully appreciated by all in the relevant fields.  It is time for the broader stellar community to see the constraints that these data provide, and a JD seems to be an excellent way to bring together the communities working on stellar spectra, stellar interiors, meteorites, and the interstellar medium.

Preliminary Scientific Program Summary:
The greatest discoveries in astronomy have accompanied technological innovations that have opened new windows of the electromagnetic spectrum.  One of the last poorly explored regions lies between 100 MHz and the ionospheric cutoff at 10 MHz.  In the past, variations in the ionosphere have limited ground-based instruments to small (<5 km) apertures and hence relatively coarse angular resolution and sensitivity.  Ever-increasing computing power combined with new calibration and imaging techniques make it possible to overcome this restriction.  New instruments such as the Long Wavelength Array (LWA) in the southwest US and the Low Frequency Array (LOFAR) in The Netherlands are being proposed for development.  As a preparation for these new instruments and as a result of new technologies, many exciting scientific results have been obtained at long wavelengths (< 1 GHz) in the past several years and continue to be generated, even with the very limited capabilities presently available.  Since the last extensive discussion of long wavelength astrophysics was held in 2004 September, and that was a relatively local meeting, it is a good time to bring the world community of interested astronomers together to discuss new results and plan for advanced instruments to fully open this poorly studies wavelength range.

Preliminary Scientific Program Summary:
The seismology and physics of localized structures beneath the surface of the Sun takes on a special significance with the completion of a solar cycle of high quality observations in 2006, at the same time that the testing of models of stellar structure moves into high gear with the extension of deep probes from the Sun to other solar-like stars and other multi-mode pulsators.  This JD will provide the forum for practitioners in these various fields to synthesize and summarize the current state of these two closely related and rapidly developing fields.

Preliminary Scientific Program Summary:
Astronomy educates people, and gives very important opportunities to young people:  In astronomy, we find a special relationship between science and technology, both the technology used in obtaining observations and the technology used in teaching.  Astronomy also leads to an understanding of the history and the nature of science, distinguishing science from pseudo sciences.  Since astronomy attracts young people to education in science and technology, we should struggle to make maximum advantage of the situation.  But in many countries, astronomy is not in the standard curricula and teachers do not receive adequate education and support.  Still, many scientific and educational societies and government agencies have produced materials and educational resources in astronomy for all educational levels.  The aims of the proposed Special Session will be to contribute to the implementation of these recommendations, introducing some innovative points of view in teaching/learning methods.  Astronomers from all countries - developed or developing - will be equally interested.
Preliminary List of Topics:
-General strategies for effective teaching
-Effective Use of Instruction and Information Technology
-Learning Science by Doing Science
-Astronomy Worldwide Education
-Practical issues connected with the implementation of the 2003 IAU Resolution

Antarctica offers a range of remarkable conditions that provide a superlative environment for the conduct of astronomy from the visible to the millimetre wavebands, as well as for high energy astrophysics experiments.  This meeting will discuss the current state of Antarctic astronomy, especially following the winter-time opening of a new high plateau facility, Concordia Station at Dome C.  The status of facilities at the South Pole and Concordia will be reviewed, and new science results presented. This will be followed by a discussion on future plans for facilities.  Finally, the meeting will provide an opportunity for discussing plans for the International Polar Year in 2007, including a possible site testing expedition to Dome A, the summit of the Antarctic plateau.
