Rationale

Scientific Rationale:

Supernovae (SNe) have a great diversity of light curves and spectral evolution. We now understand that the diversity of core-collapse SNe (Types II, Ib, Ic) is determined largely by the history of mass loss from the progenitor star, which determines the distribution of circumstellar matter and the structure of the star immediately before the supernova event. Thus the evolution of the supernova progenitor may have a great influence on the subsequent evolution of X-ray and radio emission from the SNR. Moreover supernova explosions can stimulate star formation by compressing interstellar gas and can also help to terminate star formation by dispersing gas in star-forming molecular clouds. Supernovae in low-density regions, such as superbubbles or galactic bulges, cannot effectively radiate energy therefore may drive global outflows, affecting the galactic ecosystem.

The unifying theme of the Symposium is the physics of shocks and the observations of their radiation in both SNe and SNRs. The observational situation is advancing rapidly. X-ray telescopes (Chandra, XMM-Newton, Suzaku) continue providing new insights into explosive nucleosynthesis and shock physics, whereas radio telescopes (such as VLA, GMRT, ATCA, MOST) have enabled the discovery and study of many young Supernovae and SNRs. Automated searches have increased the discovery rate of extragalactic SNe by more than an order of magnitude, enabling multi-wavelength follow-up observations by many kinds of telescopes on the ground and in space.


The IAU symposium aims to provide a coherent conceptual framework for interpreting this rich observational harvest, to establish an agenda for guiding future research, and to attract young scientists into this rapidly advancing field.
