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. 715 (2010) 596-605 arXiv:1004.1186 Inspirehep.net, Kaavioita. The setup is 230 light-years away. [13], Coordinates: 12h 07m 33.47s, −39° 32′ 54.0″. [6] Still glowing red hot, it will shrink to a size slightly smaller than Jupiter as it cools over the next few billion years. Feb 18, 2016. An initial photometric estimate for the distance to 2M1207 was 70 parsecs. [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. 228 light-years.

This was later confirmed by ultraviolet spectroscopy. a young brown dwarf." of a cloud of gas and dust. The system 2M1207 lies at a distance of 230 light-years, in … R. A. 2. We detect emission from dust continuum at 0.89mm and from the J =-3 2 rotational transition of CO from a very compact disk around the young brown dwarf. in Sep 2004. [3] The companion, 2M1207b, is estimated to have a mass of 3–10 Jupiter masses. Recent trigonometric parallax results have confirmed this moving cluster distance, leading to a distance estimate of 53 ± 1 parsec or 172 ± 3 light years. A team of European and American scientists working It was imaged the first time by the VLT in 2004. Wikipedia The disk structure for SSSPM 1102 is found to be very similar to the known brown dwarf disk 2MASSW J1207334-393254 (2M1207), with excess emission observed at wavelengths as short as 5 μm. It is believed to be from 3 to 10 times the mass of Jupiterand may orbit 2M1207 at a distance roughly as far from the b… Composite of an exoplanet orbiting the 2M1207 brown dwarf star. Chauvin G., Lagrange A.-M., Dumas C., Zuckerman B., Mouillet D., Song 2M1207 (brown dwarf) It orbits the brown dwarf at a distance 55 times larger than the Earth to the Sun, nearly twice as far as Neptune is from the Sun. Its estimated mass is around 25 Jupiter masses. [7] The new distance gives a fainter luminosity for 2M1207. 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. Chauvin G., Lagrange A.-M., Dumas C., Zuckerman B., Mouillet D., Song Figure2. 2M1207 is a brown dwarf around which orbits the first exoplanet ever to be directly photographed. Astron. it may have formed the same way our Sun formed, by gravitational collapse It was discovered in April 2004 by the Very Large Telescope (VLT) at the Paranal Observatory in Chile by a team from the European Southern Observatory led by Gaël Chauvin.

Feb 18, 2016. & Astrophys., We detect emission from dust continuum at 0.89mm and from the J =-3 2 rotational transition of CO from a very compact disk around the young brown dwarf. One of the first candidate exoplanets to be directly observed . angle of 125:8oin H, K and L0. Planetary-mass object orbiting the brown dwarf 2M1207, in the constellation Centaurus, approximately 170 light-years from Earth. Object Description . The relative disc mass for 2M1207 [log(M disc/M∗) = −2.4] is comparable to the weakly accreting systems in the TW Hydrae Association (TWA), such as Hen 3-600. [9] The existence of a dust disk has also been confirmed by infrared observations. 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 size of Jupiter and is orbiting at a The brown dwarf 2M1207 has approximately 25 times the mass of Jupiter and is thus about 42 times lighter than the Sun. HST-COS OBSERVATIONS AND DATA REDUCTION 2M1207 was observed with the medium resolution far-UV modes (G130M and G160M) of HST-COS on 2009 December 08 for a total of 16333 seconds. Close-in rocky worlds around brown dwarfs are likewise a possibility, given that we’ve already identified planets at the brown dwarfs 2M1207, 2MASS J044144, and MOA-2007-BLG-192L, with the latter being roughly 3.3 Earth masses (this one was detected by gravitational microlensing, and is the smallest exoplanet I know of around a brown dwarf). first exoplanet ever to be directly Image of a planetary-mass object in orbit around brown dwarf 2M1207, taken by a group of astronomers led by Gael Chauvin in July of 2004. Le Campion, Inseok Song, and B. Zuckerman. The setup is 230 light-years away. [8][9] 2M1207 was first suspected to have such a disk because of its broad Hα line. As a member of the TW Hydrae Association, it is about eight million years old. This composite image shows an exoplanet (the red spot on the lower left), orbiting the brown dwarf 2M1207 (centre). Object Description . A brown dwarf goat kid standing in the pasture. The relative disc mass for 2M1207 [log(M disc/M∗) = −2.4] is comparable to the weakly accreting systems in the TW Hydrae Association (TWA), such as Hen 3-600. , 2008 ) Feb 18, 2016 Jupiter mass, brown dwarf star Teixeira, Daigne!
