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.

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

ANALYTICAL INVESTIGATION OF THE DECREASE IN THE SIZE OF THE HABITABLE ZONE DUE TO A LIMITED CO₂ OUTGASSING RATE. [PDF]

Astrophys J, 2016
The habitable zone concept is important because it focuses the scientific search for extraterrestrial life and aids the planning of future telescopes. Recent work has shown that planets near the outer edge of the habitable zone might not actually be able

Hot moons and cool stars

EPJ Web of Conferences, 2013
The exquisite photometric precision of the Kepler space telescope now puts the detection of extrasolar moons at the horizon. Here, we firstly review observational and analytical techniques that have recently been proposed to find exomoons.

Bioverse: Assessing the Ability of Direct Imaging Surveys to Empirically Constrain the Habitable Zone via Trends in Albedo

The Astronomical Journal
Will future direct imaging missions such as NASA’s upcoming Habitable Worlds Observatory (HWO) be able to understand Earth-sized planets as a population?

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.

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

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 ...

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 ...
