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 ...

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 ...

Exploring and Validating Exoplanet Atmospheric Retrievals with Solar System Analog Observations
The Planetary Science Journal, 2023 Solar system observations that serve as analogs for exoplanet remote sensing data can provide important opportunities to validate ideas and models related to exoplanet environments.

Evaluating the persistence and utility of five wild Vitis species in the context of climate change
Molecular Ecology, Volume 31, Issue 24, Page 6457-6472, December 2022., 2022 Abstract Crop wild relatives (CWRs) have the capacity to contribute novel traits to agriculture. Given climate change, these contributions may be especially vital for the persistence of perennial crops, because perennials are often clonally propagated and consequently do not evolve rapidly.

The Abundance of Belatedly Habitable Planets and Ambiguities in Definitions of the Continuously Habitable Zone [PDF]
, 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. However, definitions of the CHZ vary in the literature and often conflict with each other. Calculating the

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.

Postulating Exoplanetary Habitability via a Novel Anomaly Detection Method [PDF]
, 2021 A profound shift in the study of cosmology came with the discovery of thousands of exoplanets and the possibility of the existence of billions of them in our Galaxy. The biggest goal in these searches is whether there are other life-harbouring planets. However, the question which of these detected planets are habitable, potentially-habitable, or maybe ...

Setting the Stage for Habitable Planets
Life, 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.

The Astrophysical Journal Supplement Series, 2023 Characterizing the interiors of rocky exoplanets is important to understand planetary populations and further investigate planetary habitability. New observable constraints and inference techniques have been explored for this purpose.

A Radiative-convective Model for Terrestrial Planets with Self-consistent Patchy Clouds
The Planetary Science Journal, 2023 Clouds are ubiquitous: they arise for every solar system planet that possesses an atmosphere and have also been suggested as a leading mechanism for obscuring spectral features in exoplanet observations.
