Terminator Habitability: The Case for Limited Water Availability on M-dwarf Planets

open access: yesThe 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 ...

On the Habitability of Teegarden’s Star Planets [PDF]

open access: yesThe Astrophysical Journal Letters, 2019
Abstract We study the habitability of the two Earth-mass planets, recently detected by the CARMENES collaboration, around the ultra-cool nearby M-dwarf ...

No Evidence for More Earth-sized Planets in the Habitable Zone of Kepler's M versus FGK Stars

open access: yesThe Astronomical Journal, 2023
Reliable detections of Earth-sized planets in the habitable zone remain elusive in the Kepler sample, even for M dwarfs. The Kepler sample was once thought to contain a considerable number of M-dwarf stars ( T _eff < 4000 K), which hosted enough Earth ...

Narrow Loophole for H2-Dominated Atmospheres on Habitable Rocky Planets around M Dwarfs

open access: yesThe Astrophysical Journal Letters, 2023
Habitable rocky planets around M dwarfs that have H _2 -dominated atmospheres, if they exist, would permit characterizing habitable exoplanets with detailed spectroscopy using JWST, owing to their extended atmospheres and small stars.

Habitable Zone Lifetime of Exoplanets around Main Sequence Stars [PDF]

open access: yes, 2013
Funding: Dean's Scholarship at the University of East Anglia.The potential habitability of newly discovered exoplanets is initially assessed by determining whether their orbits fall within the circumstellar habitable zone of their star.

Life at the end of worlds : modelling the biosignatures of microbial life in diverse environments at the end of the habitable lifetimes of Earth-like planets [PDF]

open access: yes, 2014
This thesis investigates how increased global mean temperatures on Earth, induced by the increase in the luminosity of the Sun as it ages, change the types of habitable environments on the planet at local scales over the next 3 Gyr.

Emergence of a Habitable Planet

open access: yesSpace Science Reviews, 2007
We address the first several hundred million years of Earth’s history. The Moon-forming impact left Earth enveloped in a hot silicate atmosphere that cooled and condensed over ∼1,000 yrs. As it cooled the Earth degassed its volatiles into the atmosphere. It took another ∼2 Myrs for the magma ocean to freeze at the surface.
