SIAMOIS, asteroseismolgy at Dome C after CoRoT

International audienceSIAMOIS is a ground-based asteroseismology project, to pursue velocity measurements from the Dome C Concordia station in Antarctica. Dome C appears to be the ideal place for ground-based asteroseismic observations as it is capable of delivering a duty cycle as high as 87% during the three-month long polar night. This high duty cycle, a crucial point for asteroseismology, is comparable to the best space-borne observations. We present the quality of the SIAMOIS project, that yields to its selection as top priority by the working group of ARENA dedicated to ``Time series observations from Dome C''. We show that, after CoRoT, SIAMOIS proposes a large scientific case, that extends the pioneering work and great discoveries of CoRoT. We depict a few important ingredients of the project: full automation, space-like philosophy, and compatibility with the current facilities at the Concordia station. SIAMOIS has no real competitor before at least 2016/2017, and can be considered as a pathfinder for many important issues concerning astronomical observations at Dome C
