Regular and chaotic orbits in axisymmetric stellar systems
R. Pascale, C. Nipoti, L. Ciotti
The gravitational potentials of realistic galaxy models are in general non-integrable, in the sense that they admit orbits that do not have three independent isolating integrals of…
An off-centred bulge or a satellite? Hydrodynamical -body simulations of the disc galaxy NGC 5474
R. Pascale, M. Bellazzini, M. Tosi +3
We present dynamical models of the star-forming galaxy NGC 5474 based on -body hydrodynamical numerical simulations. We investigate the possible origin of the compact round stel…
Survey of ortho-HD in high-mass star-forming regions
G. Sabatini, S. Bovino, A. Giannetti +7
(Abridged) We present a large sample of o-HD observations in high-mass star-forming regions and discuss possible empirical correlations with relevant physical quantities to…
The strange case of the peculiar spiral galaxy NGC5474. New pieces of a galactic puzzle
M. Bellazzini, F. Annibali, M. Tosi +5
We present the first analysis of the stellar content of the structures and substructures identified in the peculiar star-forming galaxy NGC5474, based on Hubble Space Telescope res…
Flattened stellar systems based on distribution functions depending on actions
Raffaele Pascale, James Binney, Carlo Nipoti
We address an issue that arises when self-consistently flattened dynamical stellar systems are constructed by adopting a distribution function (DF) that depends on the action integ…
Action-based models for dwarf spheroidal galaxies and globular clusters
Raffaele Pascale, James Binney, Carlo Nipoti +1
A new family of self-consistent DF-based models of stellar systems is explored. The stellar component of the models is described by a distribution function (DF) depending on the ac…
