Stellar Encounters with the Beta Pictoris Planetesimal System
Paul Kalas, Jean-Marc Deltorn, John Larwood
We use data from the Hipparcos Catalog and the Barbier-Brossat & Figon (2000) catalog of stellar radial velocities to test the hypothesis that the Beta Pic planetesimal disk was di…
Close stellar encounters with planetesimal discs: The dynamics of asymmetry in the Beta Pictoris system
J. D. Larwood, P. G. Kalas
We numerically investigate the dynamics of how a close stellar fly-by encounter of a symmetrical circumstellar planetesimal disc can give rise to the many kinds of asymmetries and…
A stellar fly-by simulation giving Beta Pic's disc asymmetries
J. Larwood, P. Kalas
We have numerically investigated the dynamics of how a close stellar fly-by encounter of a symmetrical circumstellar planetesimal disc can give rise to the many kinds of asymmetrie…
Rings in the Planetesimal Disk of Beta Pic
P. Kalas, J. Larwood, B. A. Smith +1
The nearby main sequence star Beta Pictoris is surrounded by an edge-on disk of dust produced by the collisional erosion of larger planetesimals. Here we report the discovery of su…
On the orbital evolution and growth of protoplanets embedded in a gaseous disc
J. C. B. Papaloizou, J. D. Larwood
We present a new computation of the linear tidal interaction of a protoplanetary core with a thin gaseous disc in which it is fully embedded. For the first time a discussion of the…
Evidence for early stellar encounters in the orbital distribution of Edgeworth-Kuiper Belt objects
S. Ida, J. D. Larwood, A. Burkert
We have investigated effects of early stellar encounters on a protoplanetary disk (planetesimal disk) and found that they can explain the high eccentricities and inclinations obser…
On the precession of accretion discs in X-ray binaries
J. Larwood
In this letter recent results on the nodal precession of accretion discs in close binaries are applied to the discs in some X-ray binary systems. The ratio between the tidally forc…
The tidal disruption of protoplanetary accretion discs
John D. Larwood
In this paper we revisit the problem of the tidal interaction occuring between a protostellar accretion disc and a secondary point mass following a parabolic trajectory. We model t…
A planet on an inclined orbit as an explanation of the warp in the Beta Pictoris disk
D. Mouillet, J. D. Larwood, J. C. B. Papaloizou +1
We consider the deformation that has recently been observed in the inner part of the circumstellar disk around Beta Pictoris with the HST. Our recent ground based adaptive optics c…
Precessing warped discs in close binary systems
J. C. B. Papaloizou, J. D. Larwood, R. P. Nelson +1
We describe some recent nonlinear three dimensional hydrodynamic simulations of accretion discs in binary systems where the orbit is circular and not necessarily coplanar with the…
The hydrodynamical response of a tilted circumbinary disc: linear theory and non-linear numerical simulations
John D. Larwood, John C. B. Papaloizou
In this paper we present an analytical and numerical study of the response of a circumbinary disc subject to the tidal-forcing of a binary with a fixed circular orbit. We consider…
The tidally induced warping, precession and truncation of accretion discs in binary systems: three-dimensional simulations
J. D. Larwood, R. P. Nelson, J. C. B. Papaloizou +1
We present the results of non linear, hydrodynamic simulations, in three dimensions, of the tidal perturbation of accretion discs in binary systems where the orbit is circular and…
