Abstract

We present the BinaMIcS project, its goals and the first BinaMIcS spectropolarimetric observations obtained with Narval at TBL and ESPaDOnS at CFHT: dedicated time-series for targeted hot and cool close double-line spectroscopic (SB2) binaries and a survey of hot close SB2 binaries. The very first results are also presented. In particular, our first survey observations seem to show a lack of magnetic fields in hot close binaries compared to single stars.
