We have recently identified a new radial migration mechanism resulting from the overlap of spiral and bar resonances in galactic disks. Here we confirm the efficiency of this mechanism in fully self-consistent, Tree-SPH simulations, as well as high-resolution pure N-body simulations. In all barred cases we clearly identify the effect of spiral-bar resonance overlap by measuring a bimodality in the changes of angular momentum in the disk, ΔL, whose maxima are near the bar's corotation and outer… Expand

A NEW MECHANISM FOR RADIAL MIGRATION IN GALACTIC DISKS: SPIRAL-BAR RESONANCE OVERLAP
While it has long been known that a large number of short-lived transient spirals can cause stellar migration, here we report that another mechanism is also effective at mixing disks of barredExpand
Signatures of radial migration in barred galaxies: Azimuthal variations in the metallicity distribution of old stars
By means of N-body simulations, we show that radial migration in galaxy disks, which is induced by bar and spiral arms, leads to significant azimuthal variations in the metallicity distribution ofExpand
The effect of radial migration on galactic disks
We study the radial migration of stars driven by recurring multi-arm spiral features in an exponential disk embedded in a dark matter halo. The spiral perturbations redistribute angular momentumExpand
Radial mixing in galactic discs: the effects of disc structure and satellite bombardment
We use a suite of numerical simulations to investigate the mechanisms and effects of radial migration of stars in disc galaxies such as the Milky Way (MW). An isolated, collisionless stellar discExpand
Radial migration in disc galaxies — I. Transient spiral structure and dynamics
We seek to understand the origin of radial migration in spiral galaxies by analysing in detail the structure and evolution of an idealized, isolated galactic disc. To understand the redistribution ofExpand
Evolution of galactic discs: multiple patterns, radial migration, and disc outskirts
We investigate the evolution of galactic disks in N-body Tree-SPH simulations. We find that disks, initially truncated a t three scalelengths, can triple their radial extent, solely driven by seExpand
Radial migration does little for Galactic disc thickening
Non-axisymmetric components, such as spirals and central bars, play a major role in shaping galactic discs. An important aspect of the disc secular evolution driven by these perturbers is the radialExpand
Stellar diffusion in barred spiral galaxies
We characterize empirically the radial diffusion of stars in the plane of a typical barred disk galaxy by calculating the local spatial diffusion coefficient and diffusion time-scale forExpand
Secular Evolution in Disk Galaxies
Disk galaxies evolve over time through processes that may rearrange both the radial mass profile and the metallicity distribution within the disk. This review of such slow changes is largely, thoughExpand

Abstract In this talk, I will present the result of high resolution numerical simulations of disk galaxies with various bulge/disk ratios evolving isolated, showing that: • Most of migration takesExpand

Implications of Stellar Migration for the Properties of Galactic Disks
Stars in disks of spiral galaxies are usually assumed to remain roughly at their birth radii. This assumption is built into decades of modeling of the evolution of stellar populations in our ownExpand
Structure in phase space associated with spiral and bar density waves in an N-body hybrid galactic disc

We consider a differentially rotating, 2D stellar disc perturbed by two steady-state spiral density waves moving at different pattern speeds. Our investigation is based on direct numericalExpand
Radial mixing in galactic discs
We show that spiral waves in galaxy discs churn the stars and gas in a manner that largely preserves the overall angular momentum distribution and leads to little increase in random motion. ChangesExpand
