VLT/NACO adaptive optics imaging of the Herbig Ae star HD 100453.

Abstract (from CDS):

We report the detection of a companion candidate to the Herbig Ae star HD 100453, using the NACO instrument at the VLT UT4. The separation between the companion candidate and HD 100453 is 1.06," and their brightness contrast is 5.1mag at Ks and 4.2mag at Brγ. We discuss the possible nature of the newly detected star based on near-infrared photometry. The photometric data are consistent with a 0.3M☉ companion to HD 100453, corresponding to a spectral type of M3-M5. This detection could have important implications for the structure of the disk around HD 100453.
