Habitable Zones and UV Habitable Zones around Host Stars [PDF]
Astrophysics and Space Science, 2010 Ultraviolet radiation is a double-edged sword to life. If it is too strong, the terrestrial biological systems will be damaged. And if it is too weak, the synthesis of many biochemical compounds can not go along.

The Habitable Zone and Extreme Planetary Orbits [PDF]
Astrobiology, 2012 The Habitable Zone for a given star describes the range of circumstellar distances from the star within which a planet could have liquid water on its surface, which depends upon the stellar properties.

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.

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.

Trojans in Habitable Zones [PDF]
Astrobiology, 2005 With the aid of numerical experiments we examined the dynamical stability of fictitious terrestrial planets in 1:1 mean motion resonance with Jovian-like planets of extrasolar planetary systems. In our stability study of the so-called "Trojan" planets in the habitable zone, we used the restricted three-body problem with different mass ratios of the ...

Extended Habitability of Exoplanets Due to Subglacial Water
The Astronomical Journal, 2023 Considering subglacial liquid water, a significant extension of the classical Habitable Zone is obtained. Elaborating on the model of Wandel it is shown how an atmosphere and liquid water could survive on tidally locked planets closely orbiting an M ...

No Evidence for More Earth-sized Planets in the Habitable Zone of Kepler's M versus FGK Stars
The Astronomical Journal, 2023 Reliable detections of Earth-sized planets in the habitable zone remain elusive in the Kepler sample, even for M dwarfs. The Kepler sample was once thought to contain a considerable number of M-dwarf stars ( T _eff < 4000 K), which hosted enough Earth ...

Prospects for the characterization of habitable planets
Comptes Rendus. Physique, 2023 With thousands of exoplanets now identified, the characterization of habitable planets and the potential identification of inhabited ones is a major challenge for the coming decades.
