Discovery of a late L dwarf: WISEP J060738.65+242953.4.


Abstract (from CDS):

We discover a late-type L dwarf, WISEP J060738.65+242953.4 (W0607+2429), by comparing the Wide-field Infrared Survey Explorer (WISE) preliminary data release to the Two Micron All Sky Survey (2MASS) in search of high proper motion objects ( ≳ 0".3/yr). W0607+2429 was found to have a proper motion of 0.57±0".02/yr. Based on colors and color-color diagrams using 2MASS and Sloan Digital Sky Survey photometry, we estimate the spectral type (optical) to be L8 within a spectral sub-type. Based on the spectral type estimated we find W0607+2429 to have a distance of 7.8+1.4_- 1.2_pc, making it one of only four very late L dwarfs within 10 pc, and the third closest L dwarf overall. This close L/T transition dwarf will play a pivotal role in resolving outstanding issues of condensate clouds of low-temperature atmospheres.
