This paper investigates the long-term orbital stability of small bodies near the central binary of the Alpha Centauri system. Test particles on circular orbits are integrated in the field of this binary for 32 000 binary periods or approximately 2.5 Myr. In the region exterior to the binary, particles with semi-major axes less than roughly three times the binary’s semi-major axis ab are unstable. Inside the binary, particles are unstable if further than 0.2 ab from the primary, with stablility…

Lidov-Kozai stability regions in the α Centauri system

The stability of planets in the α  Centauri AB stellar system has been studied extensively. However, most studies either focus on the orbital plane of the binary or consider inclined circular orbits.

Terrestrial Planet Formation in the α Centauri System

We examine the late stages of terrestrial planet formation around each star in the α Centauri A and α Centauri B binary system. Each integration begins with a "bimodal" mass distribution of 14 large

Formation of terrestrial planets in close binary systems: The case of alpha Centauri A

At present the possible existence of planets around the stars of a close binary system is still matter of debate. Can planetary bodies form in spite of the strong gravitational perturbations of the

Long-Term Stability of Planets in Binary Systems

A simple question of celestial mechanics is investigated: in what regions of phase space near a binary system can planets persist for long times? The planets are taken to be test particles moving in

Long-term Stability of Planets in the α Centauri System. II. Forced Eccentricities

We extend our study of the extent of the regions within the α Centauri AB star system where small planets are able to orbit for billion-year timescales to investigate the effects of minimizing the

Dynamical Stability and Habitability of the γ Cephei Binary-Planetary System

It has been suggested that the long-lived residual radial velocity variations observed in the precision radial velocity measurements of the primary of γ Cephei (HR 8974, HD 222404, HIP 116727) are

On the stability of circumbinary planetary systems

The dynamics of circumbinary planetary systems (the systems in which the planets orbit a central binary) with a small binary mass ratio discovered to date is considered. The domains of chaotic motion

Planetary Dynamics in the α Centauri System: Lyapunov Spectra and Long-term Behaviour

Abstract The stability of planetary motion in the binary system α Cen A–B is studied. Lyapunov spectra of the motion of the system with a single massive planet are computed on a fine grid of the

Long-term Stability of Tightly Packed Multi-planet Systems in Prograde, Coplanar, Circumstellar Orbits within the α Centauri AB System

We perform long-term simulations, up to ten billion years, of closely spaced configurations of 2–6 planets, each as massive as the Earth, traveling on nested orbits about either stellar component in

Evolution of α Centauri b’s protoplanetary disc

With hydrodynamical simulations we examine the evolution of a protoplanetary disc around $\alpha$ Centauri B including the effect of the eccentric orbit binary companion $\alpha$ Centauri A. The



Orbital coplanarity in solar-type binary systems: Implications for planetary system formation and detection

The equatorial inclinations of solar-type stars within visual binary systems are computed by combining v sin i measurements with rotational period information, or with expected rotational velocities

Stability criteria for triple stars

A wide variety of equal-mass stellar triple systems has been numerically integrated in order to establish factors pertinent to stability. The significant parameters appear to be whether the relative

On Predicting Long-Term Orbital Instability: A Relation Between the Lyapunov Time and Sudden Orbital Transitions

In three examples representative of Solar System dynamics, we find that the Lyapunov time, T L (i.e., the inverse of the Lyapunov exponent) and the time for an orbit to make a sudden transition T C

Cometary ray closing rates - Comet Kobayashi-Berger-Milon

The binary system α Cen A and B, with its well known parallaxe, its high quality orbit and the reasonable hypothesis of a common origin and age for both components, is a useful test of stellar

Habitable zones about main sequence stars

The space orientation of stars.

Stellar rotation periods recently determined from short-term variations in Ca II H and K emission-line flux associated with starspot activity can be combined with both rotational

This volume collects reference information for astronomers and astrophysicists, ranging from fundamental physical constants to orbital data for selected asteroids. For the Earth and planets, it

The Double Stars

The observation of the double stars upon a well-arranged list perhaps offers as favourable opportunities for rendering themselves really useful and for doing really good work in astronomy without the labour of one kind or another involved in several other classes of observation as it is possible to find.

Symplectic maps for the N-body problem.

The present study generalizes the mapping method of Wisdom (1982) to encompass all gravitational n-body problems with a dominant central mass. The rationale for the generalized mapping method is
