Investigating the Nature of Variable Class I and Flat Spectrum Protostars Using 2-4m Spectroscopy
Tracy L. Beck
In this study I present new K and L-band infrared photometry and 2-4m spectra of ten Class I and flat spectrum stars forming within the Taurus dark cloud complex. Nine source…
Discovery of a High Proper Motion L Dwarf Binary: 2MASS J15200224-4422419AB
Adam J. Burgasser, Dagny L. Looper, J. Davy Kirkpatrick +1
We report the discovery of the wide L1.5+L4.5 binary 2MASS J15200224-4422419AB, identified during spectroscopic followup of high proper motion sources selected from the Two Micron…
The Effect of Cluster Environment on Galaxy Evolution in the Pegasus I Cluster
Lorenza Levy, James A. Rose, Jacqueline H. van Gorkom +1
We present HI observations of 54 galaxies in the Pegasus cluster. The observations include single dish HI measurements, obtained with the Arecibo telescope for all 54 galaxies in t…
The Physical Properties of HD 3651B: An Extrasolar Nemesis?
Adam J. Burgasser
I present detailed analysis of the near infrared spectrum of HD 3651B, a faint, co-moving wide companion to the nearby planet-hosting star HD 3651. These data confirm the companion…
Binaries and the L Dwarf/T Dwarf Transition
Adam J. Burgasser
High-resolution imaging has revealed an unusually high binary fraction amongst objects spanning the transition between the L dwarf and T dwarf spectral classes. In an attempt to re…
Characterizing Young Brown Dwarfs using Low Resolution Near-IR Spectra
K. N. Allers, D. T. Jaffe, K. L. Luhman +7
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 Cham…
