R. Astron. 2017 : 2M1207 is a system composed of a brown dwarf with a compact disk (9.4 AU radius with 0.1 Earth mass) and a planetary-mass companion at 40 AU. Plainly, if young brown dwarfs behave like similar temperature, older field brown dwarfs, then the observed 2M1207 Hα emission should result in X-ray activity well above our limits. http://en.wikipedia.org/wiki/2M1207 5,000,000-10,000,000 years old for this brown dwarf... No, not really. We detect emission from dust continuum at 0.89 mm and from the J=3-2 rotational transition of CO from a very compact disk around the young brown dwarf. This was later confirmed by ultraviolet spectroscopy. Designated “Giant Planet Candidate Companion” by the discoverers, it may represent the first image of an exoplanet. 2M1207 wurde im Jahr 2004 entdeckt und damals zuerst vorläufig, nach den 2MASS-Regeln, ... Song, I. et al. growth and dust settling within the disk of the young brown dwarf CFHT BD Tau 4, the best characterized BD disk up to date (Pascucci et al. [3] In December 2005, American astronomer Eric Mamajek [fr] reported a more accurate distance (53 ± 6 parsecs) to 2M1207 using the moving cluster method. The brown dwarf, catalogued as 2M1207 and just 8 million years old, is 42 times less massive than the Sun, or some 25 times heftier than Jupiter. 12h 7m 33.46s Dec. 39° 32' 53.99" Constellation . This is a composite image of the brown dwarf object 2M1207 (centre) and the fainter object seen near it, at an angular distance of 778 milliarcsec.

[11] This has also been observed for 2M1207; an April 2007 paper in the Astrophysical Journal reports that this brown dwarf is spouting jets of material from its poles. from 2M1207, young 8 Myr BD of TWA Continuum-subtracted PV diagram of the [OI] 6300A line. We present new far-ultraviolet observations of the young M8 brown dwarf 2MASS J12073346- 3932539, which is surrounded by an accretion disk. This illustration shows an artist’s impression of the brown dwarf 2MASSW J1207334-393254, or 2M1207 for short. 2M1207, 2M1207A or 2MASS J12073346-3932539 is a brown dwarf located in the constellation Centaurus; a companion object, 2M1207b, may be the first extrasolar planetary-mass companion to be directly imaged, and is the first discovered orbiting a brown dwarf.[4][5]. Object Description . The data were obtaine. 422, L6–L10 (2012) (hereafter Riaz et al. The likelihood of companionship, the age and the distance of the system and the mass predicted from several evolutionary models are finally discussed. An initial photometric estimate for the distance to 2M1207 was 70 parsecs. We have also analyzed the archival PACS data and find no detection for either source in t he 160µm band. 2M1207, 2M1207A or 2MASSWJ 1207334-393254 is a brown dwarf star located at in the constellation Hydra; a companion object, 2M1207b, is believed to be one of the first extrasolar planets to be directly imaged, and is the first exoplanet to be discovered in orbit of a brown dwarf.. The brown dwarf 2M1207 has approximately 25 times the mass of Jupiter and is thus about 42 times lighter than the Sun. most probably did not form like the planets in our solar system. Viitattu 28.10.2018 (englanniksi). The data were obtained using the Hubble Space Telescope-Cosmic Origins … Observations and Data Analysis We obtained SPIRE photometric observations for SS1102 and 2M1207 in the 250, 350 and 500µm bands, using the small map mode (ObsID: 1342234825/1342223257).The small map mode We present new far-ultraviolet observations of the young M8 brown dwarf 2MASS J12073346-3932539, which is surrounded by an accretion disk.

In this paper we report high-quality MIR photometry of two bona-fide BDs, namely ChaHα1 and 2MASS1207-3932 (in the following 2M1207), obtained with the Thermal-Region Download this stock image: Composite of an exoplanet orbiting the 2M1207 brown dwarf star - PH4J1M from Alamy's library of millions of high resolution stock photos, illustrations and vectors. Turning the model around, the observed X-ray limits suggests that less than ∼ 5˚A of H α, or < 20% of the observed emission, can be due to a traditional chromosphere. An isolated object with less than about 13 Jupiter masses is technically a sub-brown dwarf or rogue planet. Brown and C. Froning and S.

Artist's View of a Super-Jupiter around a Brown Dwarf (2M1207) This is an artist impression of a planet that is four times the mass of Jupiter and orbits 8 billion kilometres from a brown-dwarf companion (the bright red object seen in the background). We present ALMA observations of the 2M1207 system, a young binary made of a brown dwarf with a planetary-mass companion at a projected separation of about 40 au. With a fairly early (for a brown dwarf) spectral type of M8,[1] it is very young, and probably a member of the TW Hydrae association. The object is no more than 30 times the mass of Jupiter, making it too small to sustain nuclear fusion to shine as a star. 2M1207, 2M1207A or 2MASS J12073346-3932539 is a brown dwarf located in the constellation Centaurus; a companion object, 2M1207b, may be the first extrasolar planetary-mass companion to be directly imaged, and is the first discovered orbiting a brown dwarf.
