Query: Search for low-mass PMS companions around X-ray selected late B stars   We have observed 49 X-ray detected bright late B-type dwarfs to search for
close low-mass pre-main sequence (PMS) companions using the European Southern
Observatory's ADONIS (Adaptive Optics Near Infrared System) instrument. We
announce the discovery of 21 new companions in 9 binaries, 5 triple, 4
quadruple system and 1 system consisting of five stars. The detected new
companions have K magnitudes between 6.5 mag and 17.3 mag. and angular
separations ranging from 0.2 and 14.1 arcsec (18-2358 AU).
