Habitable zones and UV habitable zones around host stars [PDF]
Astrophysics and Space Science, 2009 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. We try to obtain the continuous ultraviolet habitable zones, and compare the ultraviolet habitable zones with the habitable zones of host ...

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 ...

Microlensing Sensitivity to Earth-mass Planets in the Habitable Zone [PDF]
Astrophys.J. 643 (2006) 1233-1238, 2006 Microlensing is one of the most powerful methods that can detect extrasolar planets and a future space-based survey with a high monitoring frequency is proposed to detect a large sample of Earth-mass planets. In this paper, we examine the sensitivity of the future microlensing survey to Earth-mass planets located in the habitable zone.

A Volcanic Hydrogen Habitable Zone [PDF]
The Astrophysical Journal Letters, 2017 Abstract The classical habitable zone (HZ) is the circular region around a star in which liquid water could exist on the surface of a rocky planet. The outer edge of the traditional N2–CO2–H2O HZ extends out to nearly ∼1.7 au in our solar system, beyond which condensation and scattering by CO2 outstrips its greenhouse capacity.

Stable habitable zones of single Jovian planet systems [PDF]
, 2017 With continued improvement in telescope sensitivity and observational techniques, the search for rocky planets in stellar habitable zones is entering an exciting era. With so many exoplanetary systems available for follow-up observations to find potentially habitable planets, one needs to prioritise the ever-growing list of candidates.

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 ...

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 ...

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.
