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 ...

Evaluating the persistence and utility of five wild Vitis species in the context of climate change
Molecular Ecology, Volume 31, Issue 24, Page 6457-6472, December 2022., 2022 Abstract Crop wild relatives (CWRs) have the capacity to contribute novel traits to agriculture. Given climate change, these contributions may be especially vital for the persistence of perennial crops, because perennials are often clonally propagated and consequently do not evolve rapidly.

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.

The Abundance of Belatedly Habitable Planets and Ambiguities in Definitions of the Continuously Habitable Zone [PDF]
, 2023 A planet's history dictates its current potential to host habitable conditions and life. The concept of the Continuously Habitable Zone (CHZ) has been used to define the region around a star most likely to host planets with long-term habitability. However, definitions of the CHZ vary in the literature and often conflict with each other. Calculating the

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 ...

Postulating Exoplanetary Habitability via a Novel Anomaly Detection Method [PDF]
, 2021 A profound shift in the study of cosmology came with the discovery of thousands of exoplanets and the possibility of the existence of billions of them in our Galaxy. The biggest goal in these searches is whether there are other life-harbouring planets. However, the question which of these detected planets are habitable, potentially-habitable, or maybe ...

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 ...

Setting the Stage for Habitable Planets
Life, 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.
