Transit Spectroscopy, Biosignature Searches, and the Myth of Perfect Stars

Transit Spectroscopy, Biosignature Searches, and the Myth of Perfect Stars

Can we detect atmospheric biosignatures in the next two decades? Only if we can meet a major, newly-recognized challenge to our studies of exoplanet atmospheric composition. Over the past years the Hubble Space Telescope has proven to be our most powerful tool to probe the atmospheres of transiting exoplanets: the comparison of spectra taken before…

Extrasolar Storms: Belts, Spots, and Waves in Brown Dwarfs

Extrasolar Storms: Belts, Spots, and Waves in Brown Dwarfs

Our new paper came out today in Science, presenting evidence for bands, zones, spots, and waves in brown dwarfs and a model that explains well several until-now mysterious changes in the brightnesses of brown dwarfs. Podcast: Learn more about our project from the Science Magazine’s podcast!   I am excited about our results because they open a new…
