Habitable Zones in Binary Star Systems: A Zoology

open access: yesGalaxies, 2020
Several concepts have been brought forward to determine where terrestrial planets are likely to remain habitable in multi-stellar environments. Isophote-based habitable zones, for instance, rely on insolation geometry to predict habitability, whereas ...

Spectroscopic Detection of Biosignatures in Natural Ice Samples as a Proxy for Icy Moons

open access: yesLife, 2023
Some of the icy moons of the solar system with a subsurface ocean, such as Europa and Enceladus, are the targets of future space missions that search for potential extraterrestrial life forms.

A Tectonic Manifesto

open access: yesPerspectives of Earth and Space Scientists, 2023
Tectonics is the scientific discipline that studies the relationship between planetary convection and surface deformation and magmatism. In recent years global tectonic regimes and planetary evolution have become foci of astronomical and planetological ...

CD-HPF: New Habitability Score Via Data Analytic Modeling

open access: yes, 2016
The search for life on the planets outside the Solar System can be broadly classified into the following: looking for Earth-like conditions or the planets similar to the Earth (Earth similarity), and looking for the possibility of life in a form known or

Constraints on the habitability of extrasolar moons [PDF]

open access: yes, 2012
Detections of massive extrasolar moons are shown feasible with the Kepler space telescope. Kepler's findings of about 50 exoplanets in the stellar habitable zone naturally make us wonder about the habitability of their hypothetical moons.

Habitability of Super-Earth Planets around Main-Sequence Stars including Red Giant Branch Evolution: Models based on the Integrated System Approach

open access: yes, 2011
In a previous study published in Astrobiology, we focused on the evolution of habitability of a 10 M_E super-Earth planet orbiting a star akin to the Sun.

Long-Term Planetary Habitability and the Carbonate-Silicate Cycle [PDF]

open access: yesAstrobiology, 2018
The potential habitability of an exoplanet is traditionally assessed by determining if its orbit falls within the circumstellar `habitable zone' of its star, defined as the distance at which water could be liquid on the surface of a planet (Kopparapu et al., 2013). Traditionally, these limits are determined by radiative-convective climate models, which
