Surface Gravities for 228 M, L, and T Dwarfs in the NIRSPEC Brown Dwarf Spectroscopic Survey
Emily C. Martin, Gregory N. Mace, Ian S. McLean +6
We combine 131 new medium-resolution (R~2000) J-band spectra of M, L, and T dwarfs from the Keck NIRSPEC Brown Dwarf Spectroscopic Survey (BDSS) with 97 previously published BDSS s…
Discoveries from a Near-infrared Proper Motion Survey using Multi-epoch 2MASS Data
J. Davy Kirkpatrick, Dagny L. Looper, Adam J. Burgasser +12
We have conducted a 4030-square-deg near-infrared proper motion survey using multi-epoch data from the Two Micron All-Sky Survey (2MASS). We find 2778 proper motion candidates, 647…
Discovery of Two Nearby, Peculiar L Dwarfs from the 2MASS Proper Motion Survey: Young or Metal-Rich?
Dagny L. Looper, J. Davy Kirkpatrick, Roc M. Cutri +9
We present the discovery of two nearby L dwarfs from our 2MASS proper motion search, which uses multi-epoch 2MASS observations covering ~4700 square degrees of sky. 2MASS J18212815…
The NIRSPEC Brown Dwarf Spectroscopic Survey II: High-Resolution J-Band Spectra of M, L and T Dwarfs
Ian S. McLean, L. Prato, Mark R. McGovern +4
We present a sequence of high resolution (R~20,000 or 15 km/s) infrared spectra of stars and brown dwarfs spanning spectral types M2.5 to T6. Observations of 16 objects were obtain…
Discovery of a Very Young Field L Dwarf, 2MASS J01415823-4633574
J. Davy Kirkpatrick, Travis S. Barman, Adam J. Burgasser +4
While following up L dwarf candidates selected photometrically from the Two Micron All Sky Survey, we uncovered an unusual object designated 2MASS J01415823-4633574. Its optical sp…
Supergravity Interactions in the SU(4)XU(1)Vacuum of Global Supersymmetry
J. Towe
It is shown that quarks and leptons can couple intrinsically to pure supergravity, preserving for this context the degeneracy of globally supersymmetric vacua, and specifically pre…
