Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Exoplanets—planets orbiting around stars other than our own Sun—appear to be common. Significant research effort is now focused on the observation and characterization of exoplanet atmospheres. Species such as water vapour, methane, carbon monoxide and carbon dioxide have been observed in a handful of hot, giant, gaseous planets, but ...

Possibilities for an Aerial Biosphere in Temperate Sub Neptune-Sized Exoplanet Atmospheres
Universe, 2021 The search for signs of life through the detection of exoplanet atmosphere biosignature gases is gaining momentum. Yet, only a handful of rocky exoplanet atmospheres are suitable for observation with planned next-generation telescopes.

Proceedings of the National Academy of Sciences, 2013 Significance Planets around other stars, or exoplanets, are now known to be common in our galaxy. Exoplanets span a much wider range of physical conditions than the planets in our solar system, and include extremely puffy gas giants to compact rocky planets that can have densities as high as that of iron. The diversity of exoplanets allows us

Search for Exoplanets with a Possible Surface Water Ocean
Physical Sciences Forum, 2023 In this work, we examined characteristics of the currently confirmed exoplanet population in order to characterize some of the crucial parameters for ocean formation.

Atmospheric circulation of exoplanets
地球与行星物理论评, 2023 To date, more than 5000 exoplanets and more than 2000 brown dwarfs have been confirmed, which shows rich diversities in many aspects. With the rapid growth of the planet family, both observational and theoretical research on exoplanet atmosphere is ...

Universe, 2023 Tidal interaction between a star and a close-in massive exoplanet causes the planetary orbit to shrink and eventually leads to tidal disruption. Understanding orbital decay in exoplanetary systems is crucial for advancing our knowledge of planetary ...

The Demographics of Exoplanets [PDF]
, 2021 In the broadest sense, the primary goal of exoplanet demographic surveys is to determine the frequency and distribution of planets as a function of as many of the physical parameters that may influence planet formation and evolution as possible, over as broad of a range of these parameters as possible.

Magnetospheres of Terrestrial Exoplanets and Exomoons: Implications for Habitability and Detection [PDF]
The Astrophysical Journal Letters, Vol. 907, L45 (2021), 2020 Characterizing habitable exoplanets and/or their moons is of paramount importance. Here we show the results of our magnetic field topological modeling which demonstrate that terrestrial exoplanet-exomoon coupled magnetospheres work together to protect the early atmospheres of both the exoplanet and the exomoon.
