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.

Statistical-likelihood Exo-Planetary Habitability Index (SEPHI) [PDF]
, 2017 A new Statistical-likelihood Exo-Planetary Habitability Index (SEPHI) is presented. It has been developed to cover the current and future features required for a classification scheme disentangling whether any discovered exoplanet is potentially ...

Salty ice and the dilemma of ocean exoplanet habitability
Nature Communications, 2022 Habitability of exoplanet’s deepest oceans could be limited by the presence of high-pressure ices at their base. New work demonstrates that efficient chemical transport within deep planetary ice mantles is possible through significant salt incorporation ...

Gaian bottlenecks and planetary habitability maintained by evolving model biospheres: the ExoGaia model [PDF]
, 2018 The search for habitable exoplanets inspires the question - how do habitable planets form? Planet habitability models traditionally focus on abiotic processes and neglect a biotic response to changing conditions on an inhabited planet.

From climate models to planetary habitability: temperature constraints for complex life [PDF]
International Journal of Astrobiology, 2016 In an effort to derive temperature-based criteria of habitability for multicellular life, we investigated the thermal limits of terrestrial poikilotherms, i.e.

Habitability of Super-Earth Planets around Other Suns: Models including Red Giant Branch Evolution [PDF]
, 2008 The unexpected diversity of exoplanets includes a growing number of super- Earth planets, i.e., exoplanets with masses of up to several Earth masses and a similar chemical and mineralogical composition as Earth. We present a thermal evolution model for a

Carbonation and decarbonation reactions: Implications for planetary habitability
American Mineralogist, 2019 The geologic carbon cycle plays a fundamental role in controlling Earth’s climate and habitability. For billions of years, stabilizing feedbacks inherent in the cycle have maintained a surface environment that could sustain life.

Counterfactuals and unphysical ceteris paribus: An explanatory fallacy [PDF]
Filozofija i Društvo, 2013 I reconsider a type of counterfactual argument often used in historical sciences on a recent widely discussed example of the so-called “rare Earth” hypothesis in planetary sciences and astrobiology.

Multiverse Predictions for Habitability: Stellar and Atmospheric Habitability
Universe, 2022 Stellar activity and planetary atmospheric properties have the potential to strongly influence habitability. To date, neither have been adequately studied in the multiverse context, so there has been no assessment of how these effects impact the ...
