Near-IR coronagraphic imaging of the companion to HR 7672.

BOCCALETTI A., CHAUVIN G., LAGRANGE A.-M. and MARCHIS F.

Abstract (from CDS):

This article presents coronagraphic images of the low-mass companion to the star HR 7672 observed at the Palomar 200 inch telescope and first detected at Gemini and Keck in the K band by Lui et al. (2002ApJ...571..519L). We obtained additional photometry in J(1.2µm), H(1.6µm) and Ks (2.2µm) bands to cover the full near-IR domain and hence to further constrain the nature of the companion. A mass estimate of 58-71MJ is derived from evolutionary models of very low-mass objects.
