Weather on the Nearest Brown Dwarfs: Resolved Simultaneous Multi-Wavelength Variability Monitoring of WISE J104915.57-531906.1AB
Beth A. Biller, Ian J. M. Crossfield, Luigi Mancini +15
We present two epochs of MPG/ESO 2.2m GROND simultaneous 6-band () photometric monitoring of the closest known L/T transition brown dwarf binary WISE J104915.57-531906.1…
Warm Ice Giant GJ 3470b. I. A Flat Transmission Spectrum Indicates a Hazy, Low-methane, and/or Metal-rich Atmosphere
Ian J. M. Crossfield, Travis Barman, Brad M. S. Hansen +1
We report our spectroscopic investigation of the transiting ice giant GJ 3470b's atmospheric transmission, and the first results of extrasolar planet observations from the new Keck…
On High-Contrast Characterization of Nearby, Short-Period Exoplanets with Giant Segmented-Mirror Telescopes
Ian J. M. Crossfield
Measurements of the frequency with which short-period planets occur around main sequence stars allows a direct prediction of the number and types of such planets that will be amena…
Re-evaluating Hot Jupiter WASP-12b: An Update
Ian J. M. Crossfield, Travis Barman, Brad M. S. Hansen +2
The hot Jupiter WASP-12b is one of the largest, hottest, and best-studied extrasolar planets. We revisit our recent analysis of WASP-12b's emission spectrum in light of near-infrar…
