On the Habitability of Aquaplanets [PDF]
Challenges, 2014 An Aquatic Habitability Index is proposed, based on Quantitative Habitability Theory, and considering a very general model for life. It is a primary habitability index, measuring habitability for phytoplankton in the first place.

Multiverse Predictions for Habitability: The Number of Stars and Their Properties
Universe, 2019 In a multiverse setting, we expect to be situated in a universe that is exceptionally good at producing life. Though the conditions for what life needs to arise and thrive are currently unknown, many will be tested in the coming decades.

Exoplanet interiors and habitability [PDF]
Advances in Physics: X, 2019 More than 1000 exoplanets with a radius smaller than twice that of the Earth are currently known, mainly thanks to space missions dedicated to the search of exoplanets.

Habitable planets around the star Gliese 581? [PDF]
, 2007 Radial velocity surveys are now able to detect terrestrial planets at habitable distance from M-type stars. Recently, two planets with minimum masses below 10 Earth masses were reported in a triple system around the M-type star Gliese 581.

Habitability of exoplanetary systems with planets observed in transit [PDF]
, 2010 (Shortened) We have used the measured properties of the stars in the 79 exoplanetary systems with one or more planets that have been observed in transit, to estimate each system's present habitability.

The habitability of super-Earths in Gliese 581 [PDF]
, 2007 Aims: The planetary system around the M star Gliese 581 consists of a hot Neptune (Gl 581b) and two super-Earths (Gl 581c and Gl 581d). The habitability of this system with respect to the super-Earths is investigated following a concept that studies the ...

Hard rock dark biosphere and habitability
Frontiers in Astronomy and Space Sciences, 2023 The discovery that most of the prokaryotic diversity and biomass on Earth resides in the deep subsurface, calls for an improved definition of habitability, which should consider the existence of dark biospheres in other planets and moons of the Solar ...

Editorial: Habitability Beyond Earth [PDF]
Frontiers in Microbiology, 2018 The question of whether Earth is a unique location for life remains one of the most enduring questions of our time. Geochemical data suggests that habitable environments may exist, or may have existed, elsewhere in the Solar System with promising targets

Current Biology, 2017 What is a habit? One problem with the concept of habit has been that virtually everyone has their own ideas of what is meant by such a term. Whilst not eschewing folk psychology, it is useful to re-examine dictionary definitions of 'habit'. The Oxford Dictionary of English defines habit as "a settled or regular tendency or practice, especially one that

Multiverse Predictions for Habitability: Planetary Characteristics
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.
