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

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 ...

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

Surrounded by Giants: Habitable Zone Stability Within the HD 141399 System
The Astronomical Journal, 2023 The search for exoplanets has revealed a diversity of planetary system architectures, the vast majority of which diverge significantly from the template of the solar system.

On the timescale forcing in astrobiology [PDF]
Serbian Astronomical Journal, 2007 We investigate the effects of correlated global regulation mechanisms, especially Galactic gamma-ray bursts (GRBs), on the temporal distribution of hypothetical inhabited planets, using simple Monte Carlo numerical experiments.

Accounting for Multiplicity in Calculating Eta Earth [PDF]
, 2019 Using the updated exoplanet population parameters of our previous study, which includes the planetary radius updates from Gaia DR2 and an inferred multiplicity distribution, we provide a revised $\eta_{\oplus}$ calculation.

A scientometric prediction of the discovery of the first potentially habitable planet with a mass similar to Earth. [PDF]
PLoS ONE, 2010 BACKGROUND: The search for a habitable extrasolar planet has long interested scientists, but only recently have the tools become available to search for such planets.

Prospects for Cryovolcanic Activity on Cold Ocean Planets
The Astrophysical Journal, 2023 We have estimated total internal heating rates and depths to possible subsurface oceans for 17 planets that may be cold ocean planets, low-mass exoplanets with equilibrium surface temperatures and/or densities that are consistent with icy surfaces and a ...

Emergence of a Habitable Planet
Space 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.
