Circumstellar habitable zones of binary-star systems in the solar neighbourhood [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 Binary and multiple systems constitute more than half of the total stellar population in the Solar neighborhood (Kiseleva-Eggleton and Eggleton 2001). Their frequent occurrence as well as the fact that more than 70 (Schneider et al. 2011) planets have already been discovered in such configurations - most noteably the telluric companion of alpha ...

CO2 Ocean Bistability on Terrestrial Exoplanets. [PDF]
J Geophys Res Planets, 2022 Abstract Cycling of carbon dioxide between the atmosphere and interior of rocky planets can stabilize global climate and enable planetary surface temperatures above freezing over geologic time. However, variations in global carbon budget and unstable feedback cycles between planetary sub‐systems may destabilize the climate of rocky exoplanets toward ...

Fear the Shadows of the Giants: On Secular Perturbations in Circumstellar Habitable Zones of Double Stars [PDF]
The Astronomical Journal, 2020 Abstract After the detection of extrasolar planets in binary- and multiple-star systems, questions arose about their dynamics and habitability. In this study we investigate a five-dimensional parameter space for wide binary stars with a massive planet beyond the habitable zone (HZ).

Circumstellar habitable zones for deep terrestrial biospheres [PDF]
Planetary and Space Science, 2013 The habitable zone (HZ) is conventionally the thin shell of space around a star within which liquid water is thermally stable on the surface of an Earth-like planet (Kasting et al., 1993). However, life on Earth is not restricted to the surface and includes a “deep biosphere” reaching several km in depth.

Water Dynamics in Highly Concentrated Salt Solutions: A Multi-Nuclear NMR Approach. [PDF]
ChemistryOpen, 2022 A multi‐nuclear NMR approach including quadrupolar nuclei is used to monitor water and ions mobility in a series of saturated salt solutions. It is shown that water can preserve a high degree of mobility inside such solutions. The results shed light on water dynamics in highly crowded environments such as phase‐separated cellular compartments enriched ...

, 2009 The concept of the Circumstellar Habitable Zone has served the scientific community well for some decades. It slips easily off the tongue, and it would be hard to replace. Recently, however, several workers have postulated types of habitable bodies which might exist outside the classic circumstellar habitable zone (HZ).

Circumbinary Habitable Zones in the Presence of a Giant Planet
Frontiers 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.
