Revised Fluxes for Gliese 229B

Abstract: We have used the coronagraphic instrument CoCo with the Infrared Telescope Facility's camera, NSFCAM, to obtain improved photometry at JHKLЈ of the giant planet/brown dwarf Gliese 229B. We have recalibrated the published spectra for this object and recalculated its luminosity. Our LЈ value and our flux calibration of the spectra at JHK are significantly different from those previously published. Our results show good agreement at all bands except H with evolutionary models by Burrows et al. which include grain… Show more

“…Extending from the red branch of the dwarf track, comprised of late M dwarfs (Leggett, Allard, & Hauschildt 1998), are L dwarfs (triangles) identiÐed in 2MASS data . At the opposite end of the main sequence track lie Gliese 229B (Leggett et al 1999 ; square) and the majority of T dwarfs (circles) identiÐed by 2MASS and SDSS. These objects lie just below the densest region of near-infrared color space, occupied by early-type (OÈG) stars. ""…”

“…L dwarf (triangles) and T dwarf (circles) colors are shown with error bars, based on 2MASS photometry. Colors for Gliese 229B (square) are taken from Leggett et al (1999). The locations of S-, C-, and M-type asteroids are indicated by hash-marked regions (Sykes et al 2000).…”

“…Carbon monoxide in GI 229B. The spectrum of GI 229B is shown as a thick solid line (Oppenheimer et al 1998;Leggett et al 1999). The 4.5 -5/-Lm spectrum is flux-calibrated using the M' photometry of Golimowski et al (2002).…”

“…Spectral Ðtting and models (e.g., Leggett, Allard, & Hauschildt 1998 ;Chabrier et al 2000 ;Marley 2000) demonstrate that this is because of the progressive appearance of more silicate dust in the cooling brown dwarf atmospheres. Yet the cooler T-type brown dwarfs, such as Gl 229B, have blue colors in J[K (e.g., Leggett et al 1999 ;Tsvetanov et al 2000). The spectra and colors of these cool brown dwarfs can only be Ðt by atmosphere models that assume the silicate dust has settled below the visible atmosphere (e.g., Allard et al 1996 ;Marley et al 1996 ;Tsuji et al 1996).…”
