Multi-band (0.9 to 1.6 um) images of the TW Hydrae Association (TWA) browndwarf, 2MASS J1207334-393254 (also known as 2M1207), and its candidateplanetary mass companion (2M1207b) were obtained on 2004 Aug 28 and 2005 Apr 26with HST/NICMOS. The images from these two epochs unequivocally confirm the twoobjects as a common proper motion pair (16.0 sigma confidence). A newmeasurement of the proper motion of 2M1207 implies a distance to the system of59+-7 pc and a projected separation of 46+-5 AU. The NICMOS and previouslypublished VLT photometry of 2M1207b, extending overall from 0.9 to 3.8 um, arefully consistent with an object of a few Jupiter masses at the canonical age ofa TWA member (~8 Myr) based on evolutionary models of young giant planets.These observations provide information on the physical nature of 2M1207b andunambiguously establish that the first direct image of a planetary masscompanion in orbit around a self-luminous body, other than our Sun, has beensecured.Comment: 18 pages, 3 figures, 3 tables.
