Map of Luhman 16B: the first global map of a brown dwarf. Bright regions are gaps in the clouds, where infrared light from the hotter, deeper atmosphere can escape to space.

Recent Results:

2014 May: Following our recent paper presenting the first global, 2D map of patchy clouds in a brown dwarf, I present a new investigation of how many other brown dwarfs or extrasolar planets might eventually be mapped in this way. The results are favorable: although no targets are as easy to map as our neighbor Luhman 16B, many brown dwarfs -- and a few planets -- will eventually be mapped using future instruments on future giant telescopes. This conclusion is further supported by an analysis recently published by Snellen et al. As part of this analysis I also compiled all previous measurements of rotation and varying brightness for brown dwarfs and exoplanets. Read all about it here.

About Me:

I am a Sagan Fellow at the Lunar and Planetary Lab at Tucson's University of Arizona. My interests lie in exoplanet formation, composition, detection, and characterization, and the development of instrumentation to further those pursuits. I am currently studying extrasolar planets using both photometry and high-resolution spectroscopy from the ground and space. I have worked for two years at the MPIA in Heidelberg, Germany and for three years at the Jet Propulsion Laboratory, and I received my doctorate from UCLA. I also maintain an online repository of useful Python computing tools.
