Probing a regular orbit with spectral dynamics
Y. Copin, H. S. Zhao, P. T. de Zeeuw
We have extended the spectral dynamics formalism introduced by Binney & Spergel, and have implemented a semi-analytic method to represent regular orbits in any potential, making fu…
Debris streams in the solar neighbourhood as relicts from the formation of the Milky Way
Amina Helmi, Simon D. M. White, P. Tim de Zeeuw +1
It is now generally believed that galaxies were built up through gravitational amplification of primordial fluctuations and the subsequent merging of smaller precursor structures.…
Can galactic nuclei be non-axisymmetric? --- The parameter space of power-law discs
HongSheng Zhao, Marcella Carollo, Tim de Zeeuw
The shape of a cusped galactic nucleus is constrained by the range of shapes of orbits in its gravitational potential. It is shown for scale-free non-axisymmetric discs that while…
