Executive Summary Download Poster: gif (0.8 Mb), pdf (7.5 Mb)
The goal of this symposium is to gather together specialists observationally studying solar and stellar lower atmospheric and coronal phenomena in the (E)UV, radio, visible light and X-ray bands and the theorists developing modelling (both analytical and numerical) of (magneto)hydrodynamic (MHD) waves and oscillations in structured media, lower atmospheric and coronal heating and atmospheric magneto-seismology to discuss the current trends of the research in the field both in the context of solar and stellar physics. The emphasis is on wave and oscillation observations in different observational bands, consolidation of the theory and the observational findings, observations with new and future solar mission, RHESSI, Solar B, STEREO and SDO.

Theoretical aspects of the Symposium
IAUS247 deals with the physics of waves and oscillations in a wide variety of solar and stellar atmospheric objects. In particular, theoretical and modelling aspects of data inversion techniques for linear and nonlinear waves and oscillations will be addressed. Specifically, the symposium programme will be devoted to these subjects:
  • waves and oscillations in solar and stellar interior (dynamo waves)
  • the coupling of global solar and stellar motions into the lower atmosphere
  • seismology of the lower solar atmosphere (e.g. small-scale fields)
  • seismology of open vs. closed magnetic structures
  • prominence oscillations
  • dynamical processes and coupling in the magnetic atmosphere of stars
  • global solar and stellar atmospheric/coronal seismology
  • fundamental physical processes in coronae: waves, turbulence, reconnection
  • waves and instabilities in atmospheric plasmas
  • wave-particle interactions in magnetized plasmas
IAUS247 will provide an excellent opportunity for an exchange of information on how these processes can be described by models and numerical simulations. Comparison with observational evidence will be made in the context of physical processes. The Symposium will also present theoretical developments initiated by the results of a new generation of instruments which have recently come into operation or are expected to have done so in the near future. In addition, it will provide a unique meeting place between researchers in the fields of solar and stellar physics to exchange experience between these fields.

Instrumental Aspects of the Symposium
We are experiencing an unprecedented golden era in solar physics. In light of the very serious recent major international commitments (e.g., Yohkoh, SOHO, TRACE, RHESSI), and the upcoming missions (Solar-B, STEREO, SDO and possibly SO) the issues of waves and oscillations, their role in the diagnostics of the lower atmosphere and corona, their role in heating mechanisms of the solar atmosphere are now extremely topical. Ground-based instrumentations from optical to radio wavelengths (e.g., USA, La Palma, Tenerife, BiSON, etc.) supported with superb magneto-vectorgram instrumentations and high-resolution rapid cameras on balloon and rocket missions have resulted in vast amounts of excellent and valuable solar data. The community has to be fully informed about the capabilities of the current and upcoming instrumentation and has to be ready to fully explore these opportunities. We will pay special attention to these mission programmes (current and upcoming ones) and will provide plenty of opportunities to the community for engagement in knowledge-transfer and for scientific exploitation. Links to stellar atmospheric research (e.g. XMM) will also be in the centre of attention in order to transfer knowledge and expertise between the various solar and stellar communities involved.

The IAUS 247 Proceedings will be made available electronically and in book form.

For the Proceedings, use has to be made of style-files provided by the IAU Publisher: Cambridge University Press. Style files and Instructions for Authors can be found at our website: http://www.iaus247.org/style_files/. Detailed instructions are in the README.txt file. Note, Invited Reviews have 11 pages, Invited Contributions or Contributions 7 pages and Poster have 4 pages allocated in the Proceedings.

The contract with CUP stipulates that Proceedings will be published six months after the Symposium. CUP needs three months for the production process, leaving the three months right after the Symposium for the Editors to complete their task. This implies that Proceedings' Editors have to request from all Authors to either email their completed manuscripts to them before the Symposium or to email the manuscripts within a month after the end of the Symposium. Please note, we will not be able to accept any manuscripts for publication after 31 October 2007.
