Characterizing Young Brown Dwarfs using Low Resolution Near-IR Spectra
K. N. Allers, D. T. Jaffe, K. L. Luhman +7
We present near-infrared (1.0-2.4 micron) spectra confirming the youth and cool effective temperatures of 6 brown dwarfs and low mass stars with circumstellar disks toward the Cham…
Young, Low-Mass Brown Dwarfs with Mid-Infrared Excesses
K. N. Allers, J. E. Kessler-Silacci, L. A. Cieza +1
We have combined new I, J, H, and Ks imaging of portions of the Chamaeleon II, Lupus I, and Ophiuchus star-forming clouds with 3.6 to 24 micron imaging from the Spitzer Legacy Prog…
Stellar Properties of Pre-Main Sequence Stars from High Resolution Near-IR Spectra
G. W. Doppmann, D. T. Jaffe, R. J. White
We present high resolution (R=50,000) spectra at 2.2 um of 16 young stars in the rho Ophiuchi dark cloud. Photospheric features are detected in the spectra of 11 of these sources,…
TEXES: A Sensitive High-Resolution Grating Spectrograph for the Mid-Infrared
J. H. Lacy, M. J. Richter, T. K. Greathouse +2
We discuss the design and performance of TEXES, the Texas Echelon Cross Echelle Spectrograph. TEXES is a mid-infrared (5-25 um) spectrograph with several operating modes: high-reso…
Low Velocity Ionized Winds from Regions Around Young O Stars
D. T. Jaffe, J. Martin-Pintado
We have observed seven ultracompact HII regions in hydrogen recombination lines in the millimeter band. Toward four of these regions, there is a high velocity (full width to half m…
Molecular Hydrogen Emission from the Inner 400 Parsecs of the Galaxy
Soojong Pak, D. T. Jaffe, L. D. Keller
We have mapped the H_2 v=1-0 S(1) (λ=2.1215 \micron) emission line along a 400 pc long strip and in a 50 pc region in the Galactic center. There is H_2 emission throughout the surv…
