Earth-size planet formation in the habitable zone of circumbinary stars [PDF]
, 2020 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 planets (totaling 22 systems) to calculate the boundaries of their respective habitable zones (HZ).

Terminator Habitability: The Case for Limited Water Availability on M-dwarf Planets
The Astrophysical Journal, 2023 Rocky planets orbiting M-dwarf stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets in the M-dwarf habitable zone are likely synchronously rotating, such that we expect significant day–night ...

Radiative habitable zones in martian polar environments [PDF]
Icarus, 2005 The biologically damaging solar ultraviolet (UV) radiation (quantified by the DNA-weighted dose) reaches the Martian surface in extremely high levels. Searching for potentially habitable UV-protected environments on Mars, we considered the polar ice caps that consist of a seasonally varying CO2 ice cover and a permanent H2O ice layer. It was found that,

Surrounded by Giants: Habitable Zone Stability Within the HD 141399 System
The Astronomical Journal, 2023 The search for exoplanets has revealed a diversity of planetary system architectures, the vast majority of which diverge significantly from the template of the solar system.

Exoplanet Searches in the Habitable Zone with Gravitational Microlensing [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractThere are different methods for finding exoplanets such as radial spectral shifts, astrometrical measurements, transits, timing, etc. Gravitational microlensing (including pixel-lensing) is among the most promising techniques with the potential of detecting Earth-like planets at distances about a few astronomical units from their host stars ...

Survival of habitable planets in unstable planetary systems [PDF]
, 2016 Many observed giant planets lie on eccentric orbits. Such orbits could be the result of strong scatterings with other giant planets. The same dynamical instability that produces these scatterings may also cause habitable planets in interior orbits to become ejected, destroyed, or be transported out of the habitable zone.

The Influence of Tidal Heating on the Habitability of Planets Orbiting White Dwarfs
The Astrophysical Journal Letters, 2023 In recent years, there have been a growing number of observations indicating the presence of rocky material in short-period orbits around white dwarfs. In this Letter, we revisit the prospects for habitability around these post-main-sequence star systems.

Effect of Metallicity on the Evolution of the Habitable Zone from the Pre-Main Sequence to the Asymptotic Giant Branch and the Search for Life [PDF]
, 2013 During the course of stellar evolution, the location and width of the habitable zone changes as the luminosity and radius of the star evolves. The duration of habitability for a planet located at a given distance from a star is greatly affected by the characteristics of the host star. A quantification of these effects can be used observationally in the
