Title | Giant planet companion to 2MASSW J1207334-393254 |
Keywords | not available |
Abstract | We report new VLT/NACO imaging observations of the young, nearby brown
dwarf 2MASSW J1207334-393254 and its suggested planetary mass
companion (2M1207 b). Three epochs of VLT/NACO measurements
obtained over nearly one year show that the planetary mass companion
candidate shares the same proper motion and, with a high confidence
level, is not a stationary background object. This result confirms the
status of 2M1207 b as of planetary mass (5 times the mass of
Jupiter) and the first image of a planetary mass companion in a
different system than our own. This discovery offers new perspectives
for our understanding of chemical and physical properties of planetary
mass objects as well as their mechanisms of formation. hide abstract |
