Submillimeter Observations of the Young Low-Mass Object IRAS 04158+2805 (2008)
Andrews, Sean M., Liu, Michael C., Williams, Jonathan P., Allers, K. N.
We present high spatial resolution Submillimeter Array observations and supplementary single-dish photometry of the molecular gas and dust around IRAS 04158+2805, a young source with spectral type...
HN Peg B: A Test of Models of the L to T Dwarf Transition (2008)
Leggett, S. K., Saumon, D., Albert, Loic, Cushing, Michael. C., Liu, Michael C., Luhman, K. L., ...
Luhman and collaborators recently discovered an early-T dwarf companion to the G0 dwarf star HN Peg, using Spitzer Infrared Array Camera (IRAC) images. Companionship was established on the basis of...
Oph 1622-2405: Not a Planetary-Mass Binary (2007)
Luhman, K. L., Allers, K. N., Jaffe, D. T., Cushing, M. C., Williams, K. A., Slesnick, C. L., ...
We present an analysis of the mass and age of the young low-mass binary Oph 1622-2405. Using resolved optical spectroscopy of the binary, we measure spectral types of M7.25+/-0.25 and M8.75+/-0.25...
Characterizing Young Brown Dwarfs using Low Resolution Near-IR Spectra (2006)
Allers, K. N., Jaffe, D. T., Luhman, K. L., Liu, Michael C., Wilson, J. C., Skrutskie, M. F., ...
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 Chamaeleon II and...
Young, Low-Mass Brown Dwarfs with Mid-Infrared Excesses (2006)
Allers, K. N., Kessler-Silacci, J. E., Cieza, L. A., Jaffe, D. T.
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 Program, "From...
Young, Jupiter-Mass Objects in Ophiuchus (2005)
Allers, K. N., Jaffe, D. T., Van Der Bliek, N. S., Allard, F., Baraffe, I.
We have used 3.5 to 8 micron data from the Cores to Disks (c2d) Legacy survey and our own deep IJHKs images of a 0.5 square degree portion of the c2d fields in Ophiuchus to produce a sample of...
H_2 Pure Rotational Lines in the Orion Bar (2005)
Allers, K. N., Jaffe, D. T., Lacy, J. H., Draine, B. T., Richter, M. J.
Using the Texas Echelon Cross Echelle Spectrograph (TEXES) we mapped emission in the H_2 v = 0-0 S(1) and S(2) lines toward the Orion Bar PDR at 2" resolution. We also observed H_2 v = 0-0 S(4) at...
