Exploring the Effects of Stellar Magnetism on the Potential Habitability of Exoplanets

The Astrophysical Journal
Considerable interest has centered on Earth-like planets orbiting in the circumstellar habitable zone (CHZ) of its star. However, the potential habitability of an exoplanet depends upon a number of additional factors, including the presence and strength ...

Survival of Terrestrial Planets in the Presence of Giant Planet Migration

, 2003
The presence of ``Hot Jupiters'', Jovian mass planets with very short orbital periods orbiting nearby main sequence stars, has been proposed to be primarily due to the orbital migration of planets formed in orbits initially much further from the parent ...

The Five Planets in the Kepler-296 Binary System All Orbit the Primary: A Statistical and Analytical Analysis [PDF]

, 2015
Kepler-296 is a binary star system with two M-dwarf components separated by 0.2 arcsec. Five transiting planets have been confirmed to be associated with the Kepler-296 system; given the evidence to date, however, the planets could in principle orbit ...

Exomoon Habitability and Tidal Evolution in Low-Mass Star Systems

, 2017
Discoveries of extrasolar planets in the habitable zone (HZ) of their parent star lead to questions about the habitability of massive moons orbiting planets in the HZ. Around low-mass stars, the HZ is much closer to the star than for Sun-like stars.

Stellar activity and planetary atmosphere evolution in tight binary star systems

, 2019
Context. In tight binary star systems, tidal interactions can significantly influence the rotational and orbital evolution of both stars, and therefore their activity evolution.

Tidal Effects on the Habitability of Exoplanets: The Case of GJ 581 d

, 2010
Tides may be crucial to the habitability of exoplanets. If such planets form around low-mass stars, then those in the circumstellar habitable zone will be close enough to their host stars to experience strong tidal forces.

Hot Moons and Cool Stars

, 2013
The exquisite photometric precision of the Kepler space telescope now puts the detection of extrasolar moons at the horizon. Here, we firstly review observational and analytical techniques that have recently been proposed to find exomoons.

Tidal Constraints on Planetary Habitability

, 2009
We review how tides may impact the habitability of terrestrial-like planets. If such planets form around low-mass stars, then planets in the circumstellar habitable zone will be close enough to their host stars to experience strong tidal forces.
