2016 Jan: Surveys for new planets using the transit and radial velocity techniques reveal the high frequency with which small, short-period planets occur around main sequence stars. However, only a few of these smaller planets can be easily observed to characterize their atmosphere; even fewer are known around low-mass M stars, though these planetary systems may be the most common in the Galaxy. Our team has discovered three small planets orbiting a bright, nearby M star using data collected by K2, the re-purposed Kepler spacecraft. These new planets likey straddle the transition region between rocky and increasingly gas-dominated compositions. Download the paper or read all about it here.

More recently, our team announced our discovery of hundreds of planet candidates from K2, including over 100 fully validated planets. These true, bona fide planets (no longer mere candidates!) provide an excellent laboratory for measuring planet masses (via RVs and TTVs), atmospheric composition (with HST and JWST), and for studying planetary habitability. This news was covered by, by Nature News, and other sources.

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.
