One of the most interesting constraints on star formation models comes from the study of multiplicity of young stars as a function of mass. While multiplicity studies of low-mass T Tauri stars have been quite exhaustive, an unbiased and systematic investigation of multiplicity among intermediate-mass Herbig Ae/Be (HAEBE) stars is still lacking. HAEBE stars have masses in between the T Tauris and the elusive high mass young stars, for which the star formation process is still not well understood. We are therefore conducting a photometric and spectroscopic survey of HAEBE stars, to detect companions, establish their physical association with the primary and investigate their properties. The frequency and degree of multiplicity of HAEBE systems will provide new constraints on their formation mechanism. Here we present preliminary results of the BVRIJHK imaging survey (2.5x2.5 arcmin^2) to study clustering around HAEBE stars.
