On the origin of eccentricities among extrasolar planets
Daniel Malmberg, Melvyn B. Davies
Most observed extrasolar planets have masses similar to, but orbits very different from, the gas giants of our solar system. Many are much closer to their parent stars than would h…
Is our Sun a Singleton?
D. Malmberg, M. B. Davies, J. E. Chambers +4
Most stars are formed in a cluster or association, where the number density of stars can be high. This means that a large fraction of initially-single stars will undergo close enco…
Close encounters in young stellar clusters: implications for planetary systems in the solar neighbourhood
Daniel Malmberg, Francesca De Angeli, Melvyn B. Davies +3
The stars that populate the solar neighbourhood were formed in stellar clusters. Through N-body simulations of these clusters, we measure the rate of close encounters between stars…
The instability of planetary systems in binaries: how the Kozai mechanism leads to strong planet-planet interactions
Daniel Malmberg, Melvyn B. Davies, John E. Chambers
In this letter we consider the evolution of a planetary system around a star inside a wide binary. We simulate numerically the evolution of the planetary orbits for both co-planar…
