Brown Dwarf Photospheres are Patchy: A Hubble Space Telescope Near-infrared Spectroscopic Survey Finds Frequent Low-level Variability
Esther Buenzli, Daniel Apai, Jacqueline Radigan +2
Condensate clouds strongly impact the spectra of brown dwarfs and exoplanets. Recent discoveries of variable L/T transition dwarfs argued for patchy clouds in at least some ultraco…
Discovery of a Visual T-Dwarf Triple System and Binarity at the L/T Transition
Jacqueline Radigan, Ray Jayawardhana, David Lafrenière +3
We present new high contrast imaging of 8 L/T transition brown dwarfs using the NIRC2 camera on the Keck II telescope. One of our targets, the T3.5 dwarf 2MASS J08381155 + 1511155,…
Luhman 16AB: A Remarkable, Variable L/T Transition Binary 2 pc from the Sun
A. J. Burgasser, J. Faherty, Y. Beletsky +12
Luhman (2013) has reported the discovery of a brown dwarf binary system only 2.01+/-0.15 pc from the Sun. The binary is well-resolved with a projected separation of 1.5", and spect…
HST Spectral Mapping of L/T Transition Brown Dwarfs Reveals Cloud Thickness Variations
Daniel Apai, Jacqueline Radigan, Esther Buenzli +3
Most directly imaged giant exoplanets are fainter than brown dwarfs with similar spectra. To explain their relative underluminosity unusually cloudy atmospheres have been proposed.…
Weather on Other Worlds I: Detection of Periodic Variability in the L3 Dwarf DENIS-P J1058.7-1548 with Precise Multi-Wavelength Photometry
Aren N. Heinze, Stanimir Metchev, Daniel Apai +7
Photometric monitoring from warm Spitzer reveals that the L3 dwarf DENIS-P J1058.7-1548 varies sinusoidally in brightness with a period of 4.25 +0.26/-0.16 hours and an amplitude o…
