Aerosols in exoplanet atmospheres
Observations of exoplanet atmospheres have shown that aerosols, like in the solar system,
are common across a variety of temperatures and planet types. The formation and …

Detection and bulk properties of the HR 8799 planets with high-resolution spectroscopy
Abstract Using the Keck Planet Imager and Characterizer, we obtained high-resolution (R∼
35,000) K-band spectra of the four planets orbiting HR 8799. We clearly detected H 2 O and …

Let the great world spin: revealing the stormy, turbulent nature of young giant exoplanet analogs with the Spitzer Space Telescope
We present a survey for photometric variability in young, low-mass brown dwarfs with the
Spitzer Space Telescope. The 23 objects in our sample show robust signatures of youth and …

A clear view of a cloudy brown dwarf companion from high-resolution spectroscopy
Direct imaging studies have mainly used low-resolution spectroscopy (R∼ 20–100) to study
the atmospheres of giant exoplanets and brown dwarf companions, but the presence of …

Highlights of exoplanetary science from Spitzer
D Deming, HA Knutson - Nature Astronomy, 2020 - nature.com
Observations of extrasolar planets were not projected to be a substantial part of the Spitzer
Space Telescope's mission when it was conceived and designed. Nevertheless, Spitzer was …
