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…
Measurement of cosmic-ray low-energy antiproton spectrum with the first BESS-Polar Antarctic flight
K. Abe, H. Fuke, S. Haino +27
The BESS-Polar spectrometer had its first successful balloon flight over Antarctica in December 2004. During the 8.5-day long-duration flight, almost 0.9 billion events were record…
MOA-cam3: a wide-field mosaic CCD camera for a gravitational microlensing survey in New Zealand
T. Sako, T. Sekiguchi, M. Sasaki +16
We have developed a wide-field mosaic CCD camera, MOA-cam3, mounted at the prime focus of the Microlensing Observations in Astrophysics (MOA) 1.8-m telescope. The camera consists o…
Discovery of an M9.5 Candidate Brown Dwarf in the TW Hydrae Association - DENIS J124514.1-442907
Dagny L. Looper, Adam J. Burgasser, J. Davy Kirkpatrick +1
We report the discovery of a fifth candidate substellar system in the ~5-10 Myr TW Hydrae Association - DENIS J124514.1-442907. This object has a NIR spectrum remarkably similar to…
SDSS J080531.84+481233.0: An Unresolved L Dwarf/T Dwarf Binary
Adam J. Burgasser
SDSS J080531.84+481233.0 is a peculiar L-type dwarf that exhibits unusually blue near-infrared and mid-infrared colors and divergent optical (L4) and near-infrared (L9.5) spectral…
Hubble and Spitzer Observations of an Edge-on Circumstellar Disk around a Brown Dwarf
K. L. Luhman, Lucia Adame, Paola D'Alessio +7
We present observations of a circumstellar disk that is inclined close to edge-on around a young brown dwarf in the Taurus star-forming region. Using data obtained with SpeX at the…
