The Air Over There: Exploring Exoplanet Atmospheres [PDF]
Elements, 2021 The atmospheric composition for a rocky exoplanet will depend strongly on the planet’s bulk composition and orbital position. Nontraditional gases may be present in the atmospheres of exceptionally hot planets. Atmospheres of more clement planets will depend on the abundance of volatiles acquired during planet formation and atmospheric removal ...

High-resolution Transmission Spectroscopy of the Terrestrial Exoplanet GJ 486b
The Astronomical Journal, 2023 Terrestrial exoplanets orbiting M-dwarf stars are promising targets for transmission spectroscopy with existing or near-future instrumentation. The atmospheric composition of such rocky planets remains an open question, especially given the high X-ray ...

The Sensitivity of Eclipse Mapping to Planetary Rotation
The Astronomical Journal, 2022 Mapping exoplanets across phases and during secondary eclipse is a powerful technique for characterizing Hot Jupiters in emission. Since these planets are expected to rotate about axes normal to their orbital planes, with rotation periods synchronized ...

The Radiation Environment of Exoplanet Atmospheres
Challenges, 2014 Exoplanets are born and evolve in the radiation and particle environment created by their host star. The host star’s optical and infrared radiation heats the exoplanet’s lower atmosphere and surface, while the ultraviolet, extreme ultraviolet and X ...

Using dimers to measure biosignatures and atmospheric pressure for terrestrial exoplanets
, 2014 We present a new method to probe atmospheric pressure on Earth-like planets using (O-O) dimers in the near-infrared. We also show that dimer features could be the most readily detectable biosignatures for Earth-like atmospheres and may even be detectable
