In this paper, the authors reported new VLT/NACO imaging observations of the young, nearby brown dwarf 2MASSW (J1207334-393254) and its suggested planetary mass companion (2M1207b).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.read more

TL;DR: In this paper, the authors highlight the potential importance of gaseous TiO and VO opacity on the highly irradiated close-in giant planets and calculate model atmospheres for these planets, including pressure-temperature profiles, spectra, and characteristic radiative time constants.

TL;DR: In this paper, a point-like signal is detected at a projected distance of 8 AU from the star, within the northeastern extension of the dust disk, which suggests a formation process by core accretion or disk instabilities rather than binary-like formation processes.

TL;DR: Using the Gemini Planet Imager, a Jupiter-like planet is discovered orbiting the ~20-million-year-old star 51 Eridani at a projected separation of 13 astronomical units and has a methane signature and is probably the smallest exoplanet that has been directly imaged.

TL;DR: In this paper, the interior of the most massive brown dwarfs is shown to develop a conductive core after ~2 Gyr which slows down their cooling, and the authors suggest the possibility of a brown dwarf dearth in J, H, and K color-magnitude diagrams around this temperature.
