A Gaian habitable zone

open access: yesMonthly 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.

The Abundance of Belatedly Habitable Planets and Ambiguities in Definitions of the Continuously Habitable Zone

open access: yesThe 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]

open access: yesNature 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

A Catalog of Habitable Zone Exoplanets

open access: yesThe 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

open access: yesGeosciences, 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.

Exoplanets beyond the Conservative Habitable Zone. I. Habitability

open access: yesThe Astrophysical Journal
The 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.

A New Definition of Exoplanet Habitability: Introducing the Photosynthetic Habitable Zone [PDF]

open access: yesThe 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

Novel Atmospheric Dynamics Shape the Inner Edge of the Habitable Zone around White Dwarfs

open access: yesThe Astrophysical Journal
White dwarfs offer a unique opportunity to search nearby stellar systems for signs of life, but the habitable zone around these stars is still poorly understood.
