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

ON THE HABITABLE ZONES OF CIRCUMBINARY PLANETARY SYSTEMS [PDF]
The 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.

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.

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 ...

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.

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 ...

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 ...
