H- and K-Band Methane Features in an L Dwarf, 2MASS 0920+35 We have obtained near-infrared spectra of three L dwarfs discovered bythe Two Micron All Sky Survey, 1506+13 (L3), 1507-16 (L5), and 0920+35(L6.5). From the comparison of the H- and K-band spectra of these Ldwarfs, we have found the presence of methane absorption in 0920+35.This implies that detectable methane absorption in the H and K bands,usually considered the signature of a T dwarf, can be present in objectsclassified optically as late L. Methane detection in L dwarfs isconsistent with the presence of a dust layer deep in the atmosphere, asthe unified model of Tsuji suggests. Based on data collected at theSubaru Telescope, which is operated by the National AstronomicalObservatory of Japan.
