Using dimers to measure biosignatures and atmospheric pressure for terrestrial exoplanets [PDF]
, 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

Abiotic ozone and oxygen in atmospheres similar to prebiotic earth [PDF]
, 2014 The search for life on planets outside our solar system will use spectroscopic identification of atmospheric biosignatures. The most robust remotely detectable potential biosignature is considered to be the detection of oxygen (O2) or ozone (O3 ...

The Planetary Science JournalAbstract A planet’s spectrum is dynamic and only represents a time-dependent snapshot of its properties. Changing atmospheric conditions due to climate and weather patterns, particularly variation in cloud cover, can significantly affect the spectrum in ways that complicate the understanding of a planet’s baseline

A Lack of Variability between Repeated Spitzer Phase Curves of WASP-43b
The Astronomical Journal, 2023 Though the global atmospheres of hot Jupiters have been extensively studied using phase curve observations, the level of time variability in these data is not well constrained.

Helium Escape in Context: Comparative Signatures of Four Close-in Exoplanets
The Astrophysical JournalObservations of escaping atmospheres on close-in exoplanets show a wide range in the strength and morphology of He I 10830 Å and H I absorption. Scaling relations attempt to link the He I signal to X-ray and UV irradiation, mass loss, and bulk planetary ...

Observational constraints of exoplanet clouds
, 2023 We entered a new era in extrasolar planets characterisation. We are indeed given access to constraints on their meteorology. New facilities have been designed specifically for exoplanet atmospheric characterisation.
