This is a composite image of the brown dwarf object 2M1207 (blue-white) and the planet 2M1207b, seen in red, located 170 light years from Earth in the constellation Centaurus. The system resides 170 light-years away from Earth. Its companion planet, known as 2M1207b, is about five times the size of Jupiter and is orbiting at a distance nearly twice as far as Neptune is from our Sun. Astron. from 2M1207, young 8 Myr BD of TWA Continuum-subtracted PV diagram of the [OI] 6300A line. 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. Hubble's image stability, high resolution, and high-contrast imaging capabilities allowed astronomers to precisely measure the planet's brightness changes as it spins. 2M1207b is a planetary-mass object orbiting the brown dwarf 2M1207, in the constellation Centaurus, approximately 170 light-years from Earth. giant planet formation. We present ALMA observations of the 2M1207 system, a young binary made of a brown dwarf with a planetarymass companion at a projected separation of about 40 au. This was later confirmed by ultraviolet spectroscopy. [12] The jets, which extend around 109 kilometers into space, were discovered using the Very Large Telescope (VLT) at the European Southern Observatory. 2M1207 wurde im Jahr 2004 entdeckt und damals zuerst vorläufig, nach den 2MASS-Regeln, ...

These files are created for viewing on your monitor. [10] In general, accretion from disks is known to produce fast-moving jets, perpendicular to the disk, of ejected material. 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. The brown dwarf 2M1207 has approximately 25 times the mass of Jupiter and is thus about 42 times lighter than the Sun.
