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

Exoplanet weather and climate regimes with clouds and thermal ionospheres [PDF]
, 2022 Context. Gaseous exoplanets are the targets that enable us to explore fundamentally our understanding of planetary physics and chemistry. With observational efforts moving from the discovery into the characterisation mode, systematic campaigns that cover

Exoplanet atmospheres: A theoretical outlook [PDF]
, 2010 With over two dozen exoplanet atmospheres observed today, the field of exoplanet atmospheres is solidly established. The highlights of exoplanet atmosphere studies include: detection of molecular spectral features; constraints on atmospheric vertical ...

The Astrophysical Journal, 2023 In order to understand the results of recent observations of exoplanets, models have become increasingly complex. Unfortunately, this increases both the computational cost and output size of said models.

Mineralogy, Structure, and Habitability of Carbon-Enriched Rocky Exoplanets: A Laboratory Approach [PDF]
Astrobiology, 2019 Carbon-enriched rocky exoplanets have been proposed around dwarf stars as well as around binary stars, white dwarfs and pulsars. However, the mineralogical make up of such planets is poorly constrained. We performed high-pressure high-temperature laboratory experiments ($P$ = 1$-$2 GPa, $T$ = 1523$-$1823 K) on carbon-enriched chemical mixtures to ...

Chemical modeling of exoplanet atmospheres [PDF]
, 2014 International audienceThe past twenty years have revealed the diversity of planets that exist in the Universe. It turned out that most of exoplanets are different from the planets of our Solar System and thus, everything about them needs to be explored ...

The IAU working definition of an exoplanet [PDF]
, 2022 International audienceIn antiquity, all of the enduring celestial bodies that were seen to move relative to the background sky of stars were considered planets.

Enhanced constraints on the interior composition and structure of terrestrial exoplanets [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 Exoplanet interior modelling usually makes the assumption that the elemental abundances of a planet are identical to those of its host star. Host stellar abundances are good proxies of planetary abundances, but only for refractory elements. This is particularly true for terrestrial planets, as evidenced by the relative differences in bulk chemical ...

, 2013 The hundreds of exoplanets that have been discovered in the past two decades offer a new perspective on planetary structure. Instead of being the archetypal examples of planets, those of our Solar System are merely possible outcomes of planetary system formation and evolution, and conceivably not even terribly common outcomes (although this remains an ...

Rocky exoplanet characterization and atmospheres [PDF]
, 2012 A decade of exoplanet search has led to surprising discoveries, from giant planets close to their star, to planets orbiting two stars, all the way to the first extremely hot, rocky worlds with potentially permanent lava on their surfaces due to the star ...
