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.

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.

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.

A decreased probability of habitable planet formation around low-mass stars [PDF]

open access: bronze, 2007
Smaller terrestrial planets (< 0.3 Earth masses) are less likely to retain the substantial atmospheres and ongoing tectonic activity probably required to support life.

Eccentricity formation and habitable planets in OGLE-06-109L system [PDF]

open access: diamondEPJ Web of Conferences, 2011
Recent observation of microlensing technique reveals two giant planets at 2.3 AU and 4.6 AU around the star OGLE-06-109L. We investigate the eccentricity formation of these two planets, and find that planetary scattering or resonance crossing may be the ...

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.

An Integrated Approach of Multi-Criteria Decision Making to Determine the Most Habitable Planet

open access: yesHighTech and Innovation Journal, 2022
Every planet in the universe has its own characteristics. These features make the planets different among themselves. For this reason, all the different properties of the planets must be evaluated at the same time when determining habitable planets. This

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.
