The Carbon-deficient Evolution of TRAPPIST-1c
The Astrophysical Journal, 2023 Transiting planets orbiting M dwarfs provide the best opportunity to study the atmospheres of rocky planets with current facilities. As JWST enters its second year of science operations, an important initial endeavor is to determine whether these rocky ...

Planetary Magnetic Fields and Habitability in Super Earths
Open Astronomy, 2018 This work seeks to summarize some special aspects of a type of exoplanets known as super-Earths (SE), and the direct influence of these aspects in their habitability.

Binary Gravitational Perturbations and Their Influence on the Habitability of Circumstellar Planets
Frontiers in Astronomy and Space Sciences, 2021 In order to assess the habitability of planets in binary star systems, not only astrophysical considerations regarding stellar and atmospheric conditions are needed, but orbital dynamics and the architecture of the system also play an important role. Due

Venus as an Anchor Point for Planetary Habitability [PDF]
arXivA major focus of the planetary science and astrobiology community is the understanding of planetary habitability, including the myriad factors that control the evolution and sustainability of temperate surface environments such as that of Earth. The few substantial terrestrial planetary atmospheres within the Solar System serve as a critical resource ...

Double Trouble: Two Transits of the Super-Earth GJ 1132 b Observed with JWST NIRSpec G395H
The Astrophysical Journal Letters, 2023 The search for rocky planet atmospheres with JWST has focused on planets transiting M dwarfs. Such planets have favorable planet-to-star size ratios, enhancing the amplitude of atmospheric features.

Mineral dust increases the habitability of terrestrial planets but confounds biomarker detection
Nature Communications, 2020 In this study, the authors investigate in the influence of atmospheric dust on the habitability of exoplanets. They find that atmospheric dust may postpone planetary water loss; for tidally locked planets in particular, dust can significantly widen the ...

Spectroscopic Detection of Biosignatures in Natural Ice Samples as a Proxy for Icy Moons
Life, 2023 Some of the icy moons of the solar system with a subsurface ocean, such as Europa and Enceladus, are the targets of future space missions that search for potential extraterrestrial life forms.

Circumbinary habitable zones in the presence of a giant planet [PDF]
arXiv, 2021 Determining habitable zones in binary star systems can be a challenging task due to the combination of perturbed planetary orbits and varying stellar irradiation conditions. The concept of "dynamically informed habitable zones" allows us, nevertheless, to make predictions on where to look for habitable worlds in such complex environments.

Characterizing Exoplanet Habitability [PDF]
, 2019 Habitability is a measure of an environment's potential to support life, and a habitable exoplanet supports liquid water on its surface. However, a planet's success in maintaining liquid water on its surface is the end result of a complex set of interactions between planetary, stellar, planetary system and even Galactic characteristics and processes ...

Frontiers in Astronomy and Space Sciences, 2020 Icy moons in our solar system are targets of interest to search for signs of life and habitability beyond Earth. They are the astrobiological aim for several developing space missions (JUICE, Europa Clipper, and Europa Lander). A further understanding of
