cds-question@unistra.frdwarf-starsinfrared-sourcesstellar-spectral-typesvisible-astronomysloan-photometryWe present near-infrared observations of 71 newly discovered L and T dwarfs, selected from imaging data of the Sloan Digital Sky Survey (SDSS) using the i-dropout technique. Sixty-five of these dwarfs have been classified spectroscopically according to the near-infrared L dwarf classification scheme of Geballe et al. (2002ApJ...564..466G) and the unified T dwarf classification scheme of Burgasser et al. (2006, Cat. <J/ApJ/637/1067>). The spectral types of these dwarfs range from L3 to T7 and include the latest types yet found in the SDSS. Six of the newly identified dwarfs are classified as early to mid-L dwarfs according to their photometric near-infrared colors, and two others are classified photometrically as M dwarfs. We also present new near-infrared spectra for five previously published SDSS L and T dwarfs, and one L dwarf and one T dwarf discovered by Burgasser et al. (2006, Cat. <J/ApJ/637/1067>) from the Two Micron All Sky Survey. The new SDSS sample includes 27 T dwarfs and 30 dwarfs with spectral types spanning the complex L-T transition (L7-T3).2006AJ....131.2722Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/2722CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.sdss.org : SDSS Home PageII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/ApJ/637/1067 : T dwarf NIR spectral classification (Burgasser+, 2006)J/AJ/127/3553 : JHK photometry and spectroscopy for L and T dwarfsJ/ApJ/564/421 : Spectra of T dwarfs.
