The satellites of extrasolar planets (exomoons) have been recently proposed as astrobiological targets. Since giant planets in the habitable zone are thought to have migrated there, it is possible that they may have captured a former terrestrial planet or planetesimal. We therefore attempt to model the dynamical evolution of a terrestrial planet captured into orbit around a giant planet in the habitable zone of a star. We find that approximately half of loose elliptical orbits result in stable…

Formation of exomoons: a solar system perspective
Satellite formation is a natural by-product of planet formation. With the discovery of numerous extrasolar planets, it is likely that moons of extrasolar planets (exomoons) will soon be discovered.
Formation, habitability, and detection of extrasolar moons.
It is shown that natural satellites in the range of 0.1-0.5 Earth mass are potentially habitable, can form within the circumplanetary debris and gas disk or via capture from a binary, and are detectable with current technology.
Exomoon habitability constrained by illumination and tidal heating.
This work identifies combinations of physical and orbital parameters for which radiative and tidal heating are strong enough to trigger a runaway greenhouse on exomoons and defines a circumplanetary "habitable edge".
Exomoon habitability constrained by energy flux and orbital stability
Context. Detecting massive satellites that orbit extrasolar planets has now become feasible, which led naturally to questions about the habitability of exomoons. In a previous study we presented
Exomoon habitability and tidal evolution in low-mass star systems
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
Capture of terrestrial-sized moons by gas giant planets.
The energetics of how terrestrial moons with masses >0.1 M possibly exist around extrasolar giant planets are considered, and it is suggested that permanent capture is only possible around planets with sizable Hill spheres that are well separated from their host stars.
The effect of multiple heat sources on exomoon habitable zones
With dozens of Jovian and super-Jovian exoplanets known to orbit their host stars in or near the stellar habitable zones, it has recently been suggested that moons the size of Mars could offer
Dynamical Effects on the Habitable Zone for Earth-like Exomoons
With the detection of extrasolar moons (exomoons) on the horizon, it is important to consider their potential for habitability. If we consider the circum stellar Habitable Zone (HZ, often described
Compared to the giant planets in the solar system, exoplanets have many remarkable properties, such as the prevalence of giant planets on eccentric orbits and the presence of hot Jupiters.
The detectability of habitable exomoons with Kepler
In this paper, the detectability of habitable exomoons orbiting around giant planets in M-dwarf systems using transit timing variations (TTVs) and transit duration variations (TDVs) with Kepler-class


Shrinking binary and planetary orbits by Kozai cycles with tidal friction
At least two arguments suggest that the orbits of a large fraction of binary stars and extrasolar planets shrank by 1-2 orders of magnitude after formation: (1) the physical radius of a star shrinks
Possibility of a photometric detection of exomoons
Aims. We examined which exo-systems contain moons that may be detected in transit. Methods. We numerically modeled transit light curves of Earth-like and giant planets that cointain moons with
Gravitational scattering as a possible origin for giant planets at small stellar distances
An alternative model for planetary migration that can account for two large orbital eccentricities of giant planets that are difficult to reconcile with a tidal-linkage model is described.
Transiting Extrasolar Planet with a Companion: Effects of Orbital Eccentricity and Inclination
Continuing work initiated in an earlier publication (Sato & Asada, 2009, PASJ, 61, L29), we consider light curves influenced by the orbital inclination and eccentricity of a companion in orbit around
On the detection of satellites of extrasolar planets with the method of transits
We compute the detection probability of satel- lites of extrasolar planets with the method of transits, un- der the assumption that the duration of the observations is at least as long as the planet
Giant Planet Formation by Gravitational Instability
The recent discoveries of extrasolar giant planets, coupled with refined models of the compositions of Jupiter and Saturn, prompt a reexamination of theories of giant planet formation. An alternative
The Exoplanet Orbit Database
We present a database of well-determined orbital parameters of exoplanets, and their host stars’ properties. This database comprises spectroscopic orbital elements measured for 427 planets orbiting
Timescales for planetary accretion and the structure of the protoplanetary disk
Abstract This paper outlines a unified scenario for Solar System formation consistent with astrophysical constraints. Jupiter's core could have grown by runaway accretion of planetesimals to a mass
Neptune's capture of its moon Triton in a binary–planet gravitational encounter
It is reported that a three-body gravitational encounter between a binary system (of ∼103-kilometre-sized bodies) and Neptune is a far more likely explanation for Triton's capture.
Transit timing effects due to an exomoon
In our previous paper, we evaluated the transit duration variation (TDV) effect for a co-aligned planet-moon system at an orbital inclination of i=90 degrees. Here, we will consider the effect for
