Terminator Habitability: The Case for Limited Water Availability on M-dwarf Planets [PDF]
The Astrophysical Journal, 2023 Rocky planets orbiting M-dwarf stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets in the M-dwarf habitable zone are likely synchronously rotating, such that we expect significant day–night ...

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

Space Science Reviews, 2023 Venus today is inhospitable at the surface, its average temperature of 750 K being incompatible to the existence of life as we know it. However, the potential for past surface habitability and upper atmosphere (cloud) habitability at the present day is ...

Habitability and Biosignatures of Hycean Worlds [PDF]
Astrophysical Journal, 2021 We investigate a new class of habitable planets composed of water-rich interiors with massive oceans underlying H2-rich atmospheres, referred to here as Hycean worlds.

Early Mars habitability and global cooling by H2-based methanogens [PDF]
Nature Astronomy, 2022 During the Noachian, Mars’ crust may have provided a favourable environment for microbial life1,2. The porous brine-saturated regolith3–5 would have created a physical space sheltered from ultraviolet and cosmic radiation and provided a solvent, whereas ...

System Architecture and Planetary Obliquity: Implications for Long-term Habitability [PDF]
Astronomical Journal, 2022 In the search for life beyond our solar system, attention should be focused on those planets that have the potential to maintain habitable conditions over the prolonged periods of time needed for the emergence and expansion of life as we know it.

Investigating Europa’s Habitability with the Europa Clipper
Space Science Reviews, 2023 The habitability of Europa is a property within a system, which is driven by a multitude of physical and chemical processes and is defined by many interdependent parameters, so that its full characterization requires collaborative investigation.

Habitability Models for Astrobiology. [PDF]
Astrobiology, 2021 Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades to study the habitability of Earth from local to global scales ...

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 ...

Nature-based solutions for atoll habitability
Philosophical Transactions of the Royal Society of London. Biological Sciences, 2022 Atoll societies have adapted their environments and social systems for thousands of years, but the rapid pace of climate change may bring conditions that exceed their adaptive capacities.
