Binaries among Herbig Ae/Be stars.

LEINERT C., RICHICHI A. and HAAS M.

Abstract (from CDS):

We have studied the circumstellar environment of 31 Herbig Ae/Be and related stars in the near infrared by means of speckle-interferometry. For the brighter objects we reach or approximate diffraction-limited resolution of ≃0.1" (typically 100 AU at the object). Of the resolved objects some show halos, some have a companion. Here we restrict ourselves to a discussion of binarity in this sample. Eleven objects have companions, five of which constitute subarcsecond binaries, mostly found by us. Although the sample is small and neither homogeneous nor complete, it indicates a similar high incidence of binaries as found in recent surveys among T Tauri stars. Where the data allow it, we discuss the nature of the companions.
