Visible Astronomy as well? Why not!

Résumé

It is quite clear that the dry and cold astronomical site of dome C has to be one of the best places on Earth, if not THE best, for infrared and submillimetric astronomical observations. In comparison with usual observatories located in more usual latitudes, the benefit to be expected in the visible range is a little less obvious. But this benefit does exist indeed. The very long days and nights of the Antarctic plateau provide a unique opportunity for extremely long and nearly uninterrupted observations. Added to the expected reduced amplitude of the stellar scintillation, this makes possible to consider the feasibility of asteroseismic observations that were envisioned only in space so far. Such night time astronomical programmes can be developed very quickly, with moderately sized telescopes, and will benefit of the first winter-over seasons at Concordia. When thinking beyond the first few winters, the unique seeing properties of the site look extremely promising for the combination of interferometry, high performance adaptative optics and stellar coronography, or very high contrast imaging, so that the direct observations of exoplanets must be considered as a possibility for future observations on this site. I briefly review here the first projects and ideas in these directions. As many of these ideas are presented during this ”visible” session, you will find details, regarding most of them, in other papers of these proceedings.
