LSR J1835+3259
LSR J1835+3259 is a nearby brown dwarf star of spectral class M8.5, located in constellation Lyra, the discovery of which was published in 2003, and it is the 3rd nearest M-type brown dwarf after DEN 1048-3956 and LP 944-020.
Distance.
Trigonometric parallax of this object, measured in 2001–2002 with the USNO 61 inch (1.5 m) reflector under US Naval Observatory (USNO) parallax program, is 0.1765 ± 0.0005 arcsec, corresponding to a
dwarf star LSR J1835+3259. The mainly red aurora was found to be a million times brighter than the Northern Lights, a result of the charged particles interacting with hydrogen in the atmosphere. It has been speculated that stellar winds may be stripping off material from the surface of the brown dwarf to produce its own electrons. Another possible explanation for the auroras is that an as-yet-undetected body around the dwarf star is throwing off material, as is the case with Jupiter and its moon Io.
