Was the Kalkarindji Continental Flood Basalt Province a Driver of Environmental Change at the Dawn of the Phanerozoic?

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.

Dynamical Habitability of Planetary Systems [PDF]

open access: yesAstrobiology, 2010
The problem of the stability of planetary systems, a question that concerns only multiplanetary systems that host at least two planets, is discussed. The problem of mean motion resonances is addressed prior to discussion of the dynamical structure of the more than 350 known planets.

Quantifying the Key Factors Affecting the Escape of Planetary Atmospheres

open access: yesThe Astrophysical Journal, 2023
The habitability of Earth-like planets is an increasingly important subject in astrophysics and in planetary sciences. Atmospheric escape plays a vital role in the evolution of the habitability of Earth-like planets.

Hard rock dark biosphere and habitability

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The discovery that most of the prokaryotic diversity and biomass on Earth resides in the deep subsurface, calls for an improved definition of habitability, which should consider the existence of dark biospheres in other planets and moons of the Solar ...

Impact of Changing Stellar and Planetary Magnetic Fields on (Exo)planetary Environments and Atmospheric Mass Loss

open access: yesThe Astrophysical Journal, 2023
The magnetic activity of a star—which modulates the stellar wind outflow—shapes the immediate environments of orbiting (exo)planets and induces atmospheric loss, thereby impacting their habitability.

Impact of stellar evolution on planetary habitability [PDF]

open access: yesEAS Publications Series, 2019
With the ever growing number of detected and confirmed exoplanets, the probability to find a planet that looks like the Earth increases continuously. While it is clear that being in the habitable zone does not imply being habitable, a systematic study of the evolution of the habitable zone is required to account for its dependence upon stellar ...

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 ...

ON THE HABITABLE ZONES OF CIRCUMBINARY PLANETARY SYSTEMS [PDF]

open access: yesThe Astrophysical Journal, 2012
The effect of the stellar flux on exoplanetary systems is becoming an increasingly important property as more planets are discovered in the Habitable Zone (HZ). The Kepler mission has recently uncovered circumbinary planets with relatively complex HZs due to the combined flux from the binary host stars.

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 ...
