A limit on eccentricity growth from global 3-D simulations of disc-planet interactions
Alex Dunhill, Richard Alexander, Phil Armitage
We present high resolution 3-D simulations of the planet-disc interaction using smoothed particle hydrodynamics, to investigate the possibility of driving eccentricity growth by th…
WD0837+185:the formation and evolution of an extreme mass ratio white dwarf-brown dwarf binary in Praesepe
S. L. Casewell, M. R. Burleigh, G. A. Wynn +6
There is a striking and unexplained dearth of brown dwarf companions in close orbits (< 3AU) around stars more massive than the Sun, in stark contrast to the frequency of stellar a…
The dispersal of protoplanetary disks around binary stars
Richard Alexander
I present models of disk evolution around young binary stars. I show that the primary factor in determining circumbinary disk lifetimes is the rate of disk photoevaporation. I also…
A Hubble Space Telescope Survey of H2 Emission in the Circumstellar Environments of Young Stars
Kevin France, Rebecca Schindhelm, Gregory J. Herczeg +8
The formation timescale and final architecture of exoplanetary systems are closely related to the properties of the molecular disks from which they form. Observations of the spatia…
Circumstellar disks and planets. Science cases for next-generation optical/infrared long-baseline interferometers
Sebastian Wolf, Fabien Malbet, Richard Alexander +10
We present a review of the interplay between the evolution of circumstellar disks and the formation of planets, both from the perspective of theoretical models and dedicated observ…
