Abstract
New results on the B[e] star HD87643 are presented here. They were obtained with a wide range of di?erent instruments, from wide-field imaging with the WFI camera, high resolution
spectroscopy with the FEROS instrument, high angular resolution imaging with the adaptive optics camera NACO, to the highest angular resolution available with AMBER on the VLTI.
We report the detection of a companion to HD87643 with AMBER, subsequently con?rmed in the NACO data. Implications of that discovery to some of the previously
diffcult-to-understand data-sets are then presented.
