A stellar evolution computer model has been used to determine changes in the luminosity L and effective temperature Te of single stars during their time on the main sequence. The range of stellar masses investigated was from 0.5 to 1.5 times that of the Sun, each with a mass fraction of metals (metallicity, Z) from 0.008 to 0.05. The extent of each star's habitable zone (HZ) has been determined from its values of L and Te. These stars form a reference framework for other main sequence stars… Expand
Evolution of the habitable zone of low-mass stars - Detailed stellar models and analytical relationships for different masses and chemical compositions
Context. The habitability of an exoplanet is assessed by determining the times at which its orbit lies in the circumstellar habita ble zone (HZ). This zone evolves with time following the stellarExpand
A simple evolutional model of Habitable Zone around host stars with various mass and low metallicity
Habitable Zone (HZ) is defined as a life existence area, where water at the surface of the terrestrial planet is in liquid phase. This is caused by the balance of flux from the host star andExpand
The Habitability of Planets Orbiting M-dwarf Stars
The prospects for the habitability of M-dwarf planets have long been debated, due to key differences between the unique stellar and planetary environments around these low-mass stars, as compared toExpand
Earth-size planet formation in the habitable zone of circumbinary stars
In this work is investigated the possibility of close-binary star systems having Earth-size planets within their habitable zones. First, we selected all known close-binary systems with confirmedExpand
Exomoon habitability and tidal evolution in low-mass star systems
Discoveries of extrasolar planets in the habitable zone (HZ) of their parent star lead to questions about the habitability of massive moons orbiting planets in the HZ. Around low-mass stars, the HZExpand
On the stability of planetary orbits in binary star systems I. The S-type orbits
Many exoplanets are discovered in binary star systems in internal or in circumbinary orbits. Whether the planet can be habitable or not depends on the possibility to maintain liquid water on itsExpand
Habitability of exoplanetary systems with planets observed in transit
We have used the measured properties of the stars in the 79 exoplanetary systems with one or more planets that have been observed in transit, to estimate each system's present habitability. SuchExpand
Impacts of stellar evolution and dynamics on the habitable zone: The role of rotation and magnetic activity
In this article, we aim to provide the community with the dependence of the habitable zone upon the stellar mass, metallicity, rotation, and for various prescriptions of the limits of the habitableExpand
Circumstellar habitable zones of binary-star systems in the solar neighbourhood
Binary and multiple systems constitute more than half of the total stellar population in the Solar neighborhood (Kiseleva-Eggleton & Eggleton 2001). Their frequent occurrence as well as the fact thatExpand
Habitability around F-type stars
Abstract We explore the general astrobiological significance of F-type main-sequence stars with masses between 1.2 and 1.5 M⊙. Special consideration is given to stellar evolutionary aspects due toExpand


Habitable zones around main sequence stars.
The results suggest that mid-to-early K stars should be considered along with G stars as optimal candidates in the search for extraterrestrial life. Expand
Prospects for Extrasolar "Earths" in Habitable Zones
We have shown that Earth-mass planets could survive in variously restricted regions of the habitable zones (HZs) of most of a sample of nine of the 102 main-sequence exoplanetary systems confirmed byExpand
The stability of the orbits of Earth-mass planets in the habitable zone of 47 Ursae Majoris
We have investigated whether Earth-mass planets could survive in the habitable zone (HZ) of the 47 Ursae Majoris system. Mixed-variable symplectic numerical integration has been used to investigateExpand
Formation of terrestrial planets in close binary systems: The case of alpha Centauri A
At present the possible existence of planets around the stars of a close binary system is still matter of debate. Can planetary bodies form in spite of the strong gravitational perturbations of theExpand
Survival of Terrestrial Planets in the Presence of Giant Planet Migration
The presence of "hot Jupiters," Jovian-mass planets with very short orbital periods orbiting nearby main-sequence stars, has been proposed to be primarily due to the orbital migration of planetsExpand
Earth-like worlds on eccentric orbits: excursions beyond the habitable zone
Many of the recently discovered extrasolar giant planets move around their stars on highly eccentric orbits, and some with e [ges ] 0·7. Systems with planets within or near the habitable zone (HZ)Expand
Formation of Planetary Systems
A recent paper by B. M. Peek is able to explain how the necessary angular momentum of the solar system, and other possible planetary systems too, can be accounted for. Expand
Habitable planets with high obliquities.
It is shown that a significant fraction of extrasolar Earth-like planets may still be habitable, even if they are subject to large obliquity fluctuations, and that Earth's climate would become regionally severe in such circumstances. Expand
Formation of Protoplanet Systems and Diversity of Planetary Systems
We investigate the formation of protoplanet systems from planetesimal disks by global (N = 5000 and 10,000 and 0.5 AU 2. The growth timescale increases with a but decreases with Σ1. Based on theExpand
The violent environment of the origin of life.
Dating of terrestrial fossils and returned lunar samples reveals that the origin of life on Earth occurred not in a quiescent, peaceful environment, but rather in a violent, impact-ridden one. ThisExpand
