Hubble infrared view of extrasolar planet candidate

Hubble infrared view of extrasolar planet candidate


Date: 10 January 2005
Satellite: Hubble
Depicts: 2MASSWJ 1207334-393254

This is a false-colour Hubble Near Infrared Camera and Multi-Object Spectrometer (NICMOS) infrared-light view of the brown dwarf star 2MASSWJ 1207334-393254 (also known as 2M1207) and giant planet companion candidate. The possible companion, estimated to be about five times the mass of Jupiter, is the magenta coloured spot at lower right. The brown dwarf's location is within the circle at the image centre.

The glare of the dwarf, which is 700 times brighter than the planet candidate (as seen at Hubble's near-infrared sensitivity) has been greatly reduced through image processing of NICMOS pictures taken at different Hubble orientations. In this picture the dwarf and candidate planet are at a minimum distance of over 3000 million kilometres apart. Further observations will be needed to confirm that the two objects are gravitationally bound. The red, green, and blue colours correspond to infrared wavelengths of (1.6, 1.1, and 0.9 μm respectively). At a temperature of only 1250 degrees Kelvin, the candidate companion object appears very red in the NICMOS images.
