Abstract (from CDS):

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.mag 5 and 17.mag 3 and angular separations ranging from 0.2" to 14.1" (18-2358AU).
