The Habitable Zone Gallery [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 2012
The Habitable Zone Gallery (www.hzgallery.org) is a new service to the exoplanet community which provides Habitable Zone (HZ) information for each of the exoplanetary systems with known planetary orbital parameters.

Habitable Zones in the Universe

open access: yesOrigins of Life and Evolution of Biospheres, 2005
Habitability varies dramatically with location and time in the universe. This was recognized centuries ago, but it was only in the last few decades that astronomers began to systematize the study of habitability.

The Habitable Zone and Extreme Planetary Orbits [PDF]

open access: yesAstrobiology, 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.

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.

Trojans in Habitable Zones [PDF]

open access: yesAstrobiology, 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 ...

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.

No Evidence for More Earth-sized Planets in the Habitable Zone of Kepler's M versus FGK Stars

open access: yesThe 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 ...

TESS Habitable Zone Star Catalog [PDF]

open access: bronzeThe Astrophysical Journal Letters, 2019
Abstract We present the Transiting Exoplanet Survey Satellite (TESS) Habitable Zone Stars Catalog, a list of 1822 nearby stars with a TESS magnitude brighter than T = 12 and reliable distances from Gaia DR2, around which the NASA’s TESS mission can detect transiting planets, which receive Earth-like irradiation.

Prospects for the characterization of habitable planets

open access: yesComptes 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.

Water Planets in the Habitable Zone: Atmospheric Chemistry, Observable Features, and the case of Kepler-62e and -62f [PDF]

open access: yes, 2013
Planets composed of large quantities of water that reside in the habitable zone are expected to have distinct geophysics and geochemistry of their surfaces and atmospheres.
