Identifying Primordial Substructure in NGC 2264
Paula S. Teixeira, Charles J. Lada, Erick T. Young +8
We present new Spitzer Space Telescope observations of the young cluster NGC2264. Observations at 24 micron with the Multiband Imaging Photometer has enabled us to identify the mos…
The Disk Fractions of Brown Dwarfs in IC 348 and Chamaeleon I
K. L. Luhman, C. J. Lada, L. Hartmann +7
Using the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope, we have obtained mid-infrared photometry for 25 and 18 low-mass members of the IC 348 and Chamaeleon I st…
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…
UBVRI Light Curves of 44 Type Ia Supernovae
Saurabh Jha, Robert P. Kirshner, Peter Challis +2
We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…
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…
