The multiplicity of exoplanet host stars. New low-mass stellar companions of the exoplanet host stars HD125612 and HD212301.

MUGRAUER M. and NEUHAEUSER R.

Abstract (from CDS):

We present new results from our ongoing multiplicity study of exoplanet host stars, carried out with SofI/NTT. We provide the most recent list of confirmed binary and triple star systems that harbor exoplanets.We use direct imaging to identify wide stellar and substellar companions as co-moving objects to the observed exoplanet host stars, whose masses and spectral types are determined with follow-up photometry and spectroscopy.We found two new co-moving companions of the exoplanet host stars HD125612 and HD212301. HD125612B is a wide M4 dwarf (0.18M☉) companion of the exoplanet host star HD125612, located about 1.5arcmin (∼4750AU of projected separation) south-east of its primary. In contrast, HD212301B is a close M3 dwarf (0.35M☉), which is found about 4.4arcsec (∼230AU of projected separation) north-west of its primary.The binaries HD125612AB and HD212301AB are new members in the continuously growing list of exoplanet host star systems of which 43 are presently known. Hence, the multiplicity rate of exoplanet host stars is about 17%.
