Generation of inclined protoplanetary discs and misaligned planets through mass accretion I: Coplanar secondary discs
M. Xiang-Gruess, P. Kroupa
We study the three-dimensional evolution of a viscous protoplanetary disc which accretes gas material from a second protoplanetary disc during a close encounter in an embedded star…
On the formation of a quasi-stationary twisted disc after a tidal disruption event
M. Xiang-Gruess, P. B. Ivanov, J. C. B. Papaloizou
We investigate misaligned accretion discs formed after tidal disruption events that occur when a star encounters a supermassive black hole. We employ the linear theory of warped ac…
Generation of highly inclined protoplanetary discs through single stellar flybys
Meng Xiang-Gruess
We study the three-dimensional evolution of a viscous protoplanetary disc which is perturbed by a passing star on a parabolic orbit. The aim is to test whether a single stellar fly…
Evolutionary outcomes for pairs of planets undergoing orbital migration and circularization: second order resonances and observed period ratios in Kepler's planetary systems
M. Xiang-Gruess, J. C. B. Papaloizou
In order to study the origin of the architectures of low mass planetary systems, we perform numerical surveys of the evolution of pairs of coplanar planets in the mass range $(1-4)…
Interaction between massive planets on inclined orbits and circumstellar discs
Meng Xiang-Gruess, John C. B. Papaloizou
We study the interaction between massive planets and a gas disc with a mass in the range expected for protoplanetary discs. We use SPH simulations to study the orbital evolution of…
Dark matter dominated dwarf disc galaxy Segue 1
Meng Xiang-Gruess, Yu-Qing Lou, Wolfgang J. Duschl
Several observations reveal that dwarf galaxy Segue 1 has a dark matter (DM) halo at least ~ 200 times more massive than its visible baryon mass of only ~ 103 solar masses. The bar…
Global non-axisymmetric perturbation configurations in a composite disc system with an isopedic magnetic field: relation between dark matter halo and magnetic field
M. Xiang-Gruess, Y. -Q. Lou, W. J. Duschl
We study global non-axisymmetric stationary perturbations of aligned and unaligned logarithmic spiral configurations in an axisymmetric composite differentially rotating disc syste…
