The ETNA mission concept: Assessing the habitability of an active ocean world

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Enceladus is an icy world with potentially habitable conditions, as suggested by the coincident presence of a subsurface ocean, an active energy source due to water-rock interactions, and the basic chemical ingredients necessary for terrestrial life ...

Climate variations on Earth-like circumbinary planets

open access: yesNature Communications, 2017
Large variations in insolation experienced by circumbinary planets raise the question of the habitability of such planets. Here, the authors show that while the changing insolation does not radically affect habitability, it does impact on the planet’s ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Mantle Flow and Anisotropy in Subduction Zones: Modeling and Clustering of Olivine Textures

open access: yesGeochemistry, Geophysics, Geosystems
The mantle near Earth's subduction zones endures intense deformation that generates anisotropic rock textures. These textures can be observed seismically and modeled geodynamically, but the complexity of this deformation makes analyses of these textures ...

Young M-dwarfs flare activity model: Towards better exoplanetary atmospheric characterisation

open access: yesAstronomy & Astrophysics

Fluorine-Rich Planetary Environments as Possible Habitats for Life

open access: yesLife, 2014
In polar aprotic organic solvents, fluorine might be an element of choice for life that uses selected fluorinated building blocks as monomers of choice for self-assembling of its catalytic polymers.

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

A Novel Metric for Assessing Climatological Surface Habitability

open access: yesThe Planetary Science Journal
Planetary surface habitability has so far been considered, in the main, on a global scale. The increasing number of 3D modelling studies of (exo)planetary climate has highlighted the need for a more nuanced understanding of surface habitability.

User-friendly carbon-cycle modelling and aspects of Phanerozoic climate change

open access: yesApplied Computing and Geosciences
Carbon-cycle modelling is essential for testing the main carbon sources and sinks as climate forcings, and we introduce and describe GEOCARB_NET, a graphical user interface for the geologic carbon and sulfur cycle model GEOCARBSULFvolc.
