Multiverse Predictions for Habitability: Planetary Characteristics [PDF]
Universe, 2022 Recent detections of potentially habitable exoplanets around sunlike stars demand increased exploration of the physical conditions that can sustain life, by whatever methods available.

Tides and the Evolution of Planetary Habitability [PDF]
Astrobiology, 2008 Tides raised on a planet by the gravity of its host star can reduce the planet's orbital semi-major axis and eccentricity. This effect is only relevant for planets orbiting very close to their host stars.

Venus as an Anchor Point for Planetary Habitability [PDF]
Nature AstronomyA major focus of the planetary science and astrobiology community is the understanding of planetary habitability, including the myriad factors that control the evolution and sustainability of temperate surface environments such as that of Earth.

History and Habitability of the LP 890-9 Planetary System [PDF]
The Planetary Science JournalWe present numerous aspects of the evolution of the LP 890-9 (SPECULOOS-2/TOI-4306) planetary system, focusing on the likelihood that planet c can support life. We find that the host star reaches the main sequence in 1 Gyr and that planet c lies close to

The Effect of Seafloor Weathering on Planetary Habitability [PDF]
The Astrophysical Journal, 2020 Conventionally, a habitable planet is one that can support liquid water on its surface. Habitability depends on temperature, which is set by insolation and the greenhouse effect, due mainly to CO2 and water vapor.

Impact of Stellar Superflares on Planetary Habitability [PDF]
The Astrophysical Journal, 2019 High-energy radiation caused by exoplanetary space weather events from planet-hosting stars can play a crucial role in conditions promoting or destroying habitability in addition to the conventional factors.

The Effect of Core Formation on Surface Composition and Planetary Habitability [PDF]
The Astrophysical Journal Letters, 2021 The melt productivity of a differentiated planet's mantle is primarily controlled by its iron content, which is itself approximated by the planet's core mass fraction (CMF).

From climate models to planetary habitability: temperature constraints for complex life [PDF]
International Journal of Astrobiology, 2016 In an effort to derive temperature-based criteria of habitability for multicellular life, we investigated the thermal limits of terrestrial poikilotherms, i.e.

Ultradeep Microbial Communities at 4.4 km within Crystalline Bedrock: Implications for Habitability in a Planetary Context [PDF]
Life, 2020 The deep bedrock surroundings are an analog for extraterrestrial habitats for life. In this study, we investigated microbial life within anoxic ultradeep boreholes in Precambrian bedrock, including the adaptation to environmental conditions and lifestyle

Habitability Models for Planetary Sciences [PDF]
, 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 ...
