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 stellar… Expand
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 and… Expand
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 to… Expand
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 confirmed… Expand
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 HZ… Expand
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 its… Expand
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. Such… Expand
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 habitable… Expand
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 that… Expand
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 to… Expand

TLDR
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
