Geophysical and Atmospheric Evolution of Habitable Planets [PDF]

Astrobiology, 2010
The evolution of Earth-like habitable planets is a complex process that depends on the geodynamical and geophysical environments. In particular, it is necessary that plate tectonics remain active over billions of years. These geophysically active environments are strongly coupled to a planet's host star parameters, such as mass, luminosity and activity,

Planets in habitable zones: [PDF]

Astronomy & Astrophysics, 2003
The recently discovered planetary system in the binary GamCep was studied concerning its dynamical evolution. We confirm that the orbital parameters found by the observers are in a stable configuration. The primary aim of this study was to find stable planetary orbits in a habitable region in this system, which consists of a double star (a=21.36 AU ...

General Relativity Can Prevent a Runaway Greenhouse on Potentially Habitable Planets Orbiting White Dwarfs

The Astrophysical Journal
Planets orbiting in the habitable zones of white dwarfs have recently been proposed as promising targets for biosignature searches. However, since the white dwarf habitable zone resides at 0.01–0.1 au, planets residing there are subject to tidal heating ...

Eccentricity formation and habitable planets in OGLE-06-109L system

EPJ Web of Conferences, 2011
Recent observation of microlensing technique reveals two giant planets at 2.3 AU and 4.6 AU around the star OGLE-06-109L. We investigate the eccentricity formation of these two planets, and find that planetary scattering or resonance crossing may be the ...

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.

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.

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.

Belatedly Habitable Planets

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 ...
