Near-IR coronagraphic imaging of the companion to HR 7672

Résumé

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 \\citet{liu02}. We obtained additional photometry in $J$($1.2\\mu m$), $H$($1.6\\mu m$) and $K_s$ ($2.2\\mu m$) bands to cover the full near-IR domain and hence to further constrain the nature of the companion. A mass estimate of 58-71$ \\mathrm{M_J}$ is derived from evolutionary models of very low-mass objects.
