The Folded-port InfraRed Echellette (FIRE) has recently been commissioned on the Magellan 6.5m Baade Telescope. This single object, near-infrared spectrometer simultaneously covers the 0.85-2.45 micron window in both cross-dispersed (R ~ 6000) or prism-dispersed (R ~ 250-350) modes. FIRE's compact configuration, high transmission optics and high quantum efficiency detector provides considerable sensitivity in the near-infrared, making it an ideal instrument for studies of cool stars and brown… Expand

Space Velocities of L- and T-type Dwarfs
We have obtained radial velocities of a sample of 18 ultracool dwarfs (M6.5-T8) using high-resolution, near-infrared spectra obtained with NIRSPEC and the Keck II telescope. We have confirmed thatExpand
ATMOSPHERIC PARAMETERS OF FIELD L AND T DWARFS
We present an analysis of the 0.95-14.5 ?m spectral energy distributions of nine field ultracool dwarfs with spectral types ranging from L1 to T4.5. Effective temperatures, gravities, and condensateExpand
HD 203030B: An Unusually Cool Young Substellar Companion near the L/T Transition
We present the discovery of a brown dwarf companion to the star HD 203030: a G8 V Solar analog with an estimated age between 130 and 400 Myr old G8 V. Separated by 11".9 (487 AU in projection) fromExpand
L AND T DWARF MODELS AND THE L TO T TRANSITION
Using a model for refractory clouds, a novel algorithm for handling them, and the latest gas-phase molecular opacities, we have produced a new series of L and T dwarf spectral and atmosphere modelsExpand
Cool Customers in the Stellar Graveyard. II. Limits to Substellar Objects around Nearby DAZ White Dwarfs
Results from a concerted Hubble Space Telescope (HST) survey of nearby white dwarfs for substellar objects are presented. A total of seven DAZ white dwarfs with distances of 18MJ. The lack ofExpand
Clouds and chemistry: Ultracool dwarf atmospheric properties from optical and infrared colors
The optical and infrared colors of L and T dwarfs are sensitive to cloud sedimentation and chemical equilibrium processes in their atmospheres. The i'-z' versus J-K color-color diagram provides aExpand
Subtle signatures of multiplicity in late-type dwarf spectra: The unresolved M8.5 + T5 binary 2MASS J03202839-0446358
Evidence is presented that 2MASS J03202839� 0446358, a late-type dwarf with discrepant optical (M8:) andExpand
Evolutionary models for solar metallicity low - mass stars: Mass - magnitude relationships and color - magnitude diagrams
We present evolutionary models for low mass stars from 0.075 to 1 M for solar-type metallicities (M/H)= 0 and -0.5. The calculations include the most recent interior physics and the latest generationExpand
Precipitating Condensation Clouds in Substellar Atmospheres
We present a method to calculate vertical profiles of particle size distributions in condensation clouds of giant planets and brown dwarfs. The method assumes a balance between turbulent diffusionExpand
