A Spitzer Space Telescope Exploration Science Program to Search for Y Dwarf Variability
Michael C. Cushing, Jesica L. Trucks, Kevin K. Hardegree-Ullman +10
We present the results of a Spitzer Space Telescope Exploration Science Program to search for and characterize variability in Y dwarfs. We observed 14 Y dwarfs over a 24 hr period…
Spitzer + HST parallaxes of 13 late T and Y dwarfs
Federico Marocco, J. Davy Kirkpatrick, Richard L. Smart +13
We present astrometric measurements for 13 cold brown dwarfs in the solar neighborhood (d < 20pc). By combining archival Spitzer data with our own Hubble Space Telescope (HST) obse…
Observed Variability at 1um and 4um in the Y0 Brown Dwarf WISEP J173835.52+273258.9
S. K. Leggett, Michael C. Cushing, Kevin K. Hardegree-Ullman +10
We have monitored photometrically the Y0 brown dwarf WISEP J173835.52+273258.9 (W1738) at both near- and mid-infrared wavelengths. This ~1 Gyr-old 400K dwarf is at a distance of 8p…
CLOUDS search for variability in brown dwarf atmospheres
B. Goldman, M. C. Cushing, M. S. Marley +21
Context: L-type ultra-cool dwarfs and brown dwarfs have cloudy atmospheres that could host weather-like phenomena. The detection of photometric or spectral variability would provid…
A Sensitive Search for Variability in Late L Dwarfs: The Quest for Weather
M. Morales-Calderon, J. R. Stauffer, J. Davy Kirkpatrick +10
We have conducted a photometric monitoring program of 3 field late-L brown dwarfs looking for evidence of non-axisymmetric structure or temporal variability in their photospheres.…
Reflected Spectra and Albedos of Extrasolar Giant Planets I: Clear and Cloudy Atmospheres
M. S. Marley, C. Gelino, D. Stephens +2
The reflected spectra of extrasolar giant planets are primarily influenced by Rayleigh scattering, molecular absorption, and atmospheric condensates. We present model geometric alb…
