The TEXES Survey For H2 Emission From Protoplanetary Disks
M. A. Bitner, M. J. Richter, J. H. Lacy +9
We report the results of a search for pure rotational molecular hydrogen emission from the circumstellar environments of young stellar objects with disks using the Texas Echelon Cr…
Stellar and Circumstellar Properties of the Pre-Main Sequence Binary GV Tau from Infrared Spectroscopy
Greg W. Doppmann, Joan R. Najita, John S. Carr
We report spatially resolved spectroscopy of both components of the low-mass pre-main-sequence binary GV Tau. High resolution spectroscopy in the K- and L-bands is used to characte…
Stellar Properties of Embedded Protostars
R. J. White, T. P. Greene, G. W. Doppmann +2
(Abridged) High dispersion spectrographs on large aperture telescopes have recently allowed observers to study the stellar and accretion properties of deeply embedded young stars,…
Searching for proto-brown dwarfs: Extending near IR spectroscopy of protostars below the hydrogen burning limit
Kevin R. Covey, Thomas P. Greene, Greg W. Doppmann +2
Recent observations of nearby star forming regions have offered evidence that young brown dwarfs undergo a period of mass accretion analogous to the T Tauri phase observed in young…
The Radial Velocity Distribution of Class I and Flat-Spectrum Protostars
Kevin R. Covey, Thomas P. Greene, Greg W. Doppmann +1
We analyze radial velocities for a sample of 31 Class I and flat spectrum protostars in Taurus-Auriga, rho Ophiuchi and Serpens for evidence of the global dynamical state of extrem…
The Physical Natures of Class I and Flat-Spectrum Protostellar Photospheres: A Near-Infrared Spectroscopic Study
G. W. Doppmann, T. P. Greene, K. R. Covey +1
We present high resolution (R = 18,000), high signal-to-noise, 2 micron spectra of 52 infrared-selected Class I and flat-spectrum young stellar objects in the Taurus-Auriga, Op…
