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 Gallery [PDF]

Publications 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.

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.

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

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.

Habitable Zones in the Universe

Origins 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 Planet Finder Calibration System [PDF]

SPIE Proceedings, 2014
We present the design concept of the wavelength calibration system for the Habitable-zone Planet Finder instrument (HPF), a precision radial velocity (RV) spectrograph designed to detect terrestrial-mass planets around M-dwarfs.

Exoplanets beyond the Conservative Habitable Zone. I. Habitability

The 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.

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.
