On the radius of habitable planets [PDF]
Astronomy & Astrophysics, 2013 The conditions that a planet must fulfill to be habitable are not precisely known. However, it is comparatively easier to define conditions under which a planet is very likely not habitable.

Biosignatures Search in Habitable Planets [PDF]
Galaxies, 2019 The search for life has had a new enthusiastic restart in the last two decades thanks to the large number of new worlds discovered. The about 4100 exoplanets found so far, show a large diversity of planets, from hot giants to rocky planets orbiting small

4. Building of a Habitable Planet [PDF]
, 2006 Except the old Jack Hills zircon crystals, it does not exit direct record of the first 500 Ma of the Earth history. Consequently, the succession of events that took place during this period is only indirectly known through geochemistry, comparison with other telluric planets, and numerical modelling. Just after planetary accretion several episodes were

Extended Habitability of Exoplanets Due to Subglacial Water
The Astronomical Journal, 2023 Considering subglacial liquid water, a significant extension of the classical Habitable Zone is obtained. Elaborating on the model of Wandel it is shown how an atmosphere and liquid water could survive on tidally locked planets closely orbiting an M ...

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

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

Research Notes of the AAS, 2021 Abstract Stars do not remain static, so their habitable zones evolve in time. Over a star's evolution, its habitable zone encompasses new planets, and it remains uncertain whether these planets can become habitable. We refer to this often overlooked class of planets as lying in the belatedly habitable zone, and stress that many planets ...

On the Habitability of Teegarden’s Star Planets [PDF]
The 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 Teegarden’s Star. With orbital periods of 4.9 and 11.4 days, both planets are likely to be within the habitable zone and
