Query: Discovery of the Young L Dwarf WISE J1741102.78-464225.5   We report the discovery of the L dwarf WISE J174102.78$-$464225.5, that was
discovered as part of a search for nearby L dwarfs using the Wide-field
Infrared Survey Explorer (WISE). The distinct triangular peak of the H-band
portion of its near-infrared spectrum and its red near-infrared colors ($J-K_S$
= 2.35$\pm$0.08 mag) are indicative of a young age. Via comparison to spectral
standards and other red L dwarfs, we estimate a near-infrared spectral type to
be L7$\pm$2 (pec). From a comparison to spectral and low-mass evolutionary
models, we determine self-consistent effective temperature, log $g$, age, and
mass values of 1450$\pm$100 K, 4.0$\pm$0.25 (cm s$^{-2}$), 10-100 Myr, and 4-21
M$_{Jup}$, respectively. With an estimated distance of 10-30 pc, we explore the
possibility that WISE J174102.78-464225.5 belongs to one of the young nearby
moving groups via a kinematic analysis and we find potential membership in the
$\beta$ Pictoris or AB Doradus associations. A trigonometric parallax
measurement and a precise radial velocity can help to secure its membership in
either of these groups.
