Time-Resolved AU-Scale Jets Traced by Masers in the IRAS 4A/B Regions of NGC1333 (2008)

Marvel, Kevin B., Wilking, Bruce A., Claussen, Mark J, Wootten, Alwyn

We present results of VLBI observations of the water masers associated with IRAS 4A and IRAS 4B in the NGC 1333 star-forming region taken in four epochs over a two month period. Both objects have...

Deep Infrared Imaging of the R Corona Australis Cloud Core (2007)

Bruce A. Wilking, Mark J. Mccaughrean, Michael G. Burton, Timothy Giblin, John T. Rayner, Hans Zinnecker

Preliminary analysis is presented for J, H, and K 0 images of the Corona Australis cloud core. Color-color and color-magnitude diagrams reveal relatively few new cluster members. We conclude that the...

HST/NICMOS Observations of NGC 1333: The Ratio of Stars to Sub-Stellar Objects (2006)

Greissl, Julia, Meyer, Michael R., Wilking, Bruce A., Fanetti, Tina, Schneider, Glenn, Greene, Thomas P., ...

We present an analysis of NICMOS photometry and low-resolution grism spectroscopy of low-mass stars and sub-stellar objects in the young star-forming region NGC 1333. Our goal is to constrain the...

HST/NICMOS Observations of NGC 1333: The Ratio of Stars to Sub-stellar Objects (2006)

Julia Greissl, Michael R. Meyer, Bruce A. Wilking, Tina Fanetti, Glenn Schneider, Thomas P. Greene, ...

We present an analysis of NICMOS photometry and low-resolution grism spectroscopy of low-mass stars and sub-stellar objects in the young star-forming region NGC 1333. Our goal is to constrain the...

Searching for proto-brown dwarfs: Extending near IR spectroscopy of protostars below the hydrogen burning limit (2005)

Covey, Kevin R., Greene, Thomas P., Doppmann, Greg W., Lada, Charles J., Wilking, Bruce A.

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 stars. Brown dwarf...

Optical Spectroscopy of the Surface Population of the rho Ophiuchi Molecular Cloud: The First Wave of Star Formation (2005)

Wilking, Bruce A., Meyer, Michael R., Robinson, John G., Greene, Thomas P.

We present the results of optical spectroscopy of 139 stars obtained with the Hydra multi-object spectrograph. The objects extend over a 1.3 square degree area surrounding the main cloud of the rho...

Low Mass Stars and Substellar Objects in the NGC 1333 Molecular Cloud (2003)

Wilking, Bruce A., Meyer, Michael R., Greene, Thomas P., Mikhail, Ayman, Carlson, Glenn

We present the results of near-infrared imaging and low-resolution near- infrared spectroscopy of low mass objects in the NGC 1333 molecular cloud. A JHK survey of an 11.4' x 11.7' area of the...

Spectroscopy of Brown Dwarf Candidates in the rho Ophiuchi Molecular Core (1998)

Wilking, Bruce A., Greene, Thomas P., Meyer, Michael R.

We present an analysis of low resolution infrared spectra for 20 brown dwarf candidates in the core of the $\rho$ Ophiuchi molecular cloud. Fifteen of the sources display absorption-line spectra...
