Setting the Stage for Habitable Planets [PDF]

open access: yesLife, 2014
Our understanding of the processes that are relevant to the formation and maintenance of habitable planetary systems is advancing at a rapid pace, both from observation and theory.

Hot moons and cool stars

open access: yesEPJ 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.

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

open access: yesThe 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 ...

Circumbinary Habitable Zones in the Presence of a Giant Planet

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Determining habitable zones in binary star systems can be a challenging task due to the combination of perturbed planetary orbits and varying stellar irradiation conditions.

Exoplanets around Red Giants: Distribution and Habitability

open access: yesGalaxies, 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.

Water Planets in the Habitable Zone: Atmospheric Chemistry, Observable Features, and the case of Kepler-62e and -62f [PDF]

open access: yes, 2013
Planets composed of large quantities of water that reside in the habitable zone are expected to have distinct geophysics and geochemistry of their surfaces and atmospheres.

Prospects for the characterization of habitable planets

open access: yesComptes Rendus. Physique, 2023
With thousands of exoplanets now identified, the characterization of habitable planets and the potential identification of inhabited ones is a major challenge for the coming decades.

Extended Habitability of Exoplanets Due to Subglacial Water

open access: yesThe 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 ...

Terminator Habitability: The Case for Limited Water Availability on M-dwarf Planets

open access: yesThe 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 ...

No Evidence for More Earth-sized Planets in the Habitable Zone of Kepler's M versus FGK Stars

open access: yesThe Astronomical Journal, 2023
Reliable detections of Earth-sized planets in the habitable zone remain elusive in the Kepler sample, even for M dwarfs. The Kepler sample was once thought to contain a considerable number of M-dwarf stars ( T _eff < 4000 K), which hosted enough Earth ...
