Abstract:

I report the detection of a companion around HD142384 from Optical Long Baseline Interferometry in the near-infrared (flux difference DeltaH~4 and separation ~20mas). HD142384 has been used as PSF reference for published observations of the well-known young star HD142527. This is now strongly discouraged.
