New wide stellar companions of exoplanet host stars.
MUGRAUER M., GINSKI C. and SEELIGER M.
Abstract (from CDS):
We present seven new widely separated companions of exoplanet host stars, detected via common proper motion, whose companionship could be confirmed with photometry, and in two cases also with follow-up spectroscopy. We derive the masses and projected separations of all detected companions, among them HD 107148 B, a further wide white dwarf companion of an exoplanet host star. The current multiplicity rate of the exoplanet host stars is found to be about 13 percent.
