Discovery of the Closest Brown Dwarf to the Sun? a Methane Rich Brown Dwarf around the Nearby

We present VLT/NACO SDI images of the very nearby star SCR 1845-6357 (hereafter SCR 1845). SCR 1845 is a recently discovered (Hambly et al. 2004) M8.5 star just 3.5 pc from the sun (Deacon et al. 2005). Using the capabilities of the unique SDI device, we discovered a substellar companion to SCR 1845 at a separation of 4 AU (1.170”±0.003” on the sky, PA=170.20◦±0.13◦) and a ∆F1(1.575 μm) of 3.57...

Characterization of the Nearby L/t Binary Brown Dwarf Wisej104915.57−531906.1 at 2 Parsecs from the Sun

WISE J104915.57−531906.1 is a L/T brown dwarf binary located 2 pc from the Sun. The pair contains the closest known brown dwarfs and is the third closest known system, stellar or sub-stellar. We report comprehensive follow-up observations of this newly uncovered system. We have determined the spectral types of both components (L8±1, for the primary, agreeing with the discovery paper; T1.5±2 for...

Discovery of a Very Nearby Brown Dwarf to the Sun: a Methane Rich Brown Dwarf Companion to the Low Mass Star Scr

We present VLT/NACO SDI images of the very nearby star SCR 1845-6357 (hereafter SCR 1845). SCR 1845 is a recently discovered (Hambly et al. 2004) M8.5 star just 3.85 pc from the Sun (Henry et al. 2006). Using the capabilities of the unique SDI device, we discovered a substellar companion to SCR 1845 at a separation of 4.5 AU (1.170”±0.003” on the sky) and fainter by 3.57±0.057 mag in the 1.575 ...

Astronomy & Astrophysics 2 MASS J 0516288 + 260738 : Discovery of the first eclipsing late K + Brown dwarf binary system ? , ,

We report the discovery of a new eclipsing system less than one arcminute south of the pulsating DB white dwarf KUV 05134+2605. The object could be identified with the point source 2MASS J0516288+260738 published by the Two Micron All Sky Survey. We present and discuss the first light curves as well as some additional colour and spectral information. The eclipse period of the system is 1.29 d, ...

The Discovery of a Second Field Methane Brown Dwarf from Sloan Digital Sky Survey Commissioning Data.

We report the discovery of a second field methane brown dwarf from the commissioning data of the Sloan Digital Sky Survey (SDSS). The object, SDSS J134646.45-003150.4 (hereafter SDSS 1346-00), was selected because of its very red color and stellar appearance. Its spectrum between 0.8 and 2.5 µm is dominated by strong absorption bands of H2O and CH4 and closely mimics those of Gliese 229B and SD...
