The effects of fly-bys on planetary systems
Daniel Malmberg, Melvyn B. Davies, Douglas C. Heggie
Most of the observed extrasolar planets are found on tight and often eccentric orbits. The high eccentricities are not easily explained by planet-formation models, which predict th…
The Impact of Stellar Collisions in the Galactic Center
M. B. Davies, R. P. Church, D. Malmberg +3
We consider whether stellar collisions can explain the observed depletion of red giants in the Galactic center. We model the stellar population with two different IMFs: 1) the Mill…
The origin of very wide binary systems
M. B. N. Kouwenhoven, S. P. Goodwin, Richard J. Parker +3
The majority of stars in the Galactic field and halo are part of binary or multiple systems. A significant fraction of these systems have orbital separations in excess of thousands…
The formation of very wide binaries
M. B. N. Kouwenhoven, S. P. Goodwin, Richard J. Parker +3
Over the last decades, numerous wide (>1000 AU) binaries have been discovered in the Galactic field and halo. The origin of these wide binaries cannot be explained by star formatio…
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…
