Near-infrared photometry and spectroscopy of L and T dwarfs the effects of temperature, clouds, and gravity. (2004)

Keywords : infrared stars - stars: fundamental parameters - stars: late-type stars: low-mass, brown dwarfs

Abstract:We present new JHK photometry on the MKO-NIR (Mauna Kea Observatories Near-Infrared) system and JHK spectroscopy for a large sample of L and T dwarfs. Photometry has been obtained for 71 dwarfs, and spectroscopy for 56. The sample comprises newly identified very red objects from the Sloan Digital Sky Survey (SDSS, http://www.sdss.org/) and known dwarfs from the SDSS and the Two Micron All Sky Survey (2MASS, Cat. <II/246>). Spectral classification has been carried out using four previously defined indices from Geballe et al. (2002ApJ...564..466G) that measure the strengths of the near infrared water and methane bands. ...(more)
