Query: Multiwavelength study of X-ray emitting A- and B-stars testing the
  companion hypothesis   We report on the first results of a multi-wavelength approach to test the
hypothesis that the X-ray emission from intermediate-mass stars is generated by
late-type magnetically active companions. Our high spatial resolution
observations of A/B-type stars in the IR using adaptive optics uncover
hypothetical companion stars at arcsecond separations from the primary. The
same targets are then followed-up in X-rays with Chandra to pinpoint the X-ray
source. Finally, those A/B-type stars that are still detected with Chandra are
studied with IR spectroscopy, where we search for temperature sensitive
features indicating the existence of even closer cool companions.
