英文摘要	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 Liu et al. ( 2002). We obtained additional photometry in J(1.2 mum), H(1.6 mum) and K-s (2.2 mum) bands to cover the full near-IR domain and hence to further constrain the nature of the companion. A mass estimate of 58-71 M-J is derived from evolutionary models of very low-mass objects.
