First Magnetic Field Detection on a Class I Protostar
Christopher M. Johns-Krull, Thomas P. Greene, Greg W. Doppmann +1
Strong stellar magnetic fields are believed to truncate the inner accretion disks around young stars, redirecting the accreting material to the high latitude regions of the stellar…
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…
