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 ...

Magnetic Fields on the Flare Star Trappist-1: Consequences for Radius Inflation and Planetary Habitability [PDF]
Astrophysical Journal, 2018 We construct evolutionary models of Trappist-1 in which magnetic fields impede the onset of convection according to a physics-based criterion. In the models that best fit all observational constraints, the photospheric fields in Tr-1 are found to be in ...

MAGNETIC FIELD AND WIND OF KAPPA CETI: TOWARD THE PLANETARY HABITABILITY OF THE YOUNG SUN WHEN LIFE AROSE ON EARTH [PDF]
, 2016 We report magnetic field measurements for κ1 Cet, a proxy of the young Sun when life arose on Earth. We carry out an analysis of the magnetic properties determined from spectropolarimetric observations and reconstruct the large-scale surface magnetic ...

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.

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 ...

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.

The occurrence of Jovian planets and the habitability of planetary systems [PDF]
Proceedings of the National Academy of Sciences, 2001 Planets of mass comparable to or larger than Jupiter's have been detected around over 50 stars, and for one such object a definitive test of its nature as a gas giant has been accomplished with data from an observed planetary transit. By virtue of their strong gravitational pull, giant planets define the dynamical and collisional environment within ...

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.
