High Inclination Planets in Multistellar Systems
P. E. Verrier, N. W. Evans
The Kozai mechanism often destabilises high inclination orbits. It couples changes in the eccentricity and inclination, and drives high inclination, circular orbits to low inclinat…
HD 98800: A most unusual debris disc
P. E. Verrier, N. W. Evans
The dynamics of planetesimals in the circumbinary debris disc of the quadruple star system HD 98800 are investigated. Evolving a spherical shell of test particles from a million ye…
Planetary Stability Zones in Hierarchical Triple Star Systems
P. E. Verrier, N. W. Evans
A symplectic integrator algorithm suitable for hierarchical triple systems is formulated and tested. The positions of the stars are followed in hierarchical Jacobi coordinates, whi…
The Monitor project: JW 380 -- a 0.26, 0.15 Msol pre main sequence eclipsing binary in the Orion Nebula Cluster
Jonathan Irwin, Suzanne Aigrain, Simon Hodgkin +14
We report the discovery of a low-mass (0.26 +/- 0.02, 0.15 +/- 0.01 Msol) pre-main-sequence eclipsing binary with a 5.3 day orbital period. JW 380 was detected as part of a high-ca…
Planets and Asteroids in the gamma Cephei System
P. E. Verrier, N. W. Evans
The binary star system gamma Cephei is unusual in that it harbours a stable giant planet around the larger star at a distance only about a tenth of that of the stellar separation.…
