Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

86Kr excess and other noble gases identify a billion-year-old radiogenically-enriched groundwater system

open access: yesNature Communications, 2022
Noble gases confirm billion-year groundwater residence times and external fluxes in deep crustal settings globally with implications for subsurface habitability and economic reservoir formation over planetary timescales both on Earth and ...

The Influence of Tidal Heating on the Habitability of Planets Orbiting White Dwarfs

open access: yesThe 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.

Salty ice and the dilemma of ocean exoplanet habitability

open access: yesNature 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

open access: yesUniverse, 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 ...

Counterfactuals and unphysical ceteris paribus: An explanatory fallacy [PDF]

open access: yesFilozofija 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.

Setting the Stage for Habitable Planets

open access: yesLife, 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.

Planetary Magnetic Fields and Habitability in Super Earths

open access: yesOpen Astronomy, 2018
This work seeks to summarize some special aspects of a type of exoplanets known as super-Earths (SE), and the direct influence of these aspects in their habitability.

Machine-learning Inferences of the Interior Structure of Rocky Exoplanets from Bulk Observational Constraints

open access: yesThe 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.
