The Astrophysical Journal, 2023 A planet’s history dictates its current potential to host habitable conditions and life. The concept of the continuously habitable zone (CHZ) has been used to define the region around a star most likely to host planets with long-term habitability ...

Carbonate-silicate cycle predictions of Earth-like planetary climates and testing the habitable zone concept [PDF]
Nature Communications, 2020 In the habitable zone concept, a planet’s carbon dioxide-water greenhouse maintains surface liquid water. Here, the authors estimate how many Earthlike exoplanets are needed to detect a relationship between stellar flux and the atmospheric carbon dioxide

Circumbinary Habitable Zones in the Presence of a Giant Planet
Frontiers in Astronomy and Space Sciences, 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.

A Catalog of Habitable Zone Exoplanets
The Astronomical Journal, 2023 The search for habitable planets has revealed many planets that can vary greatly from an Earth analog environment. These include highly eccentric orbits, giant planets, different bulk densities, relatively active stars, and evolved stars.

A More Comprehensive Habitable Zone for Finding Life on Other Planets
Geosciences, 2018 The habitable zone (HZ) is the circular region around a star(s) where standing bodies of water could exist on the surface of a rocky planet. Space missions employ the HZ to select promising targets for follow-up habitability assessment.

A New Definition of Exoplanet Habitability: Introducing the Photosynthetic Habitable Zone [PDF]
The Astrophysical Journal Letters, 2023 It may be possible to detect biosignatures of photosynthesis in an exoplanet’s atmosphere. However, such a detection would likely require a dedicated study, occupying a large amount of telescope time. It is therefore prudent, while searching for signs of

Exoplanets beyond the Conservative Habitable Zone. I. Habitability
The Astrophysical JournalThe Habitable Zone (HZ) is defined by the possibility of sustaining liquid water on a planetary surface. In the solar system, the HZ for a conservative climate model extends approximately between the orbits of Earth and Mars.

Exoplanets around Red Giants: Distribution and Habitability
Galaxies, 2023 As the search for exoplanets continues, more are being discovered orbiting Red Giant stars. We use current data from the NASA Exoplanet Archive to investigate planet distribution around Red Giant stars and their presence in the host’s habitable zone.

Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACTWhen searching for inhabited exoplanets, understanding the boundaries of the habitable zone around the parent star is the key. If life can strongly influence its global environment, then we would expect the boundaries of the habitable zone to be influenced by the presence of life.
