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…
Outbursts and stellar properties of the classical Be star HD 6226
Noel D. Richardson, Olivier Thizy, Jon E. Bjorkman +58
The bright and understudied classical Be star HD 6226 has exhibited multiple outbursts in the last several years during which the star grew a viscous decretion disk. We analyze 659…
A Spectroscopic Orbit for the late-type Be star CMi
Nick Dulaney, Noel D. Richardson, Cody J. Gerhartz +12
The late-type Be star CMi is remarkably stable compared to other Be stars that have been studied. This has led to a realistic model of the outflowing Be disk by Klement et al.…
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…
The First Detection of Photometric Variability in a Y Dwarf: WISE J140518.39+553421.3
Michael C. Cushing, Kevin K. Hardegree-Ullman, Jesica L. Trucks +8
We present the first detection of photometric variability of a spectroscopically-confirmed Y dwarf. The Infrared Array Camera on board the Spitzer Space Telescope was used to obtai…
