Orbital integration fully accounting for the effect of the Milky Way rotating bar: emergence of the resonant loci

The field of galactic archaeology has seen a tremendous expansion in the last decade thanks to the influx of data, mainly from the ESA Gaia mission. This has prompted a rapid advance of both models and analysis techniques to extract all the available information content of the data.

Dynamical studies of stellar populations and globular clusters are based on the orbital integration technique, which uses the 6D phase space information of a tracer to reconstruct its orbital history with an underlying potential model. This allows to derive orbital parameters, integrals of motion and other dynamical parameters. All of these are used to characterise and classify stellar and globular cluster populations in the Milky Way.

In this talk I will show how it is important to update the models used in orbital integration tools to account for the full effect of the rotating bar of the Milky Way and how we can identify the effect of bar-induced resonances on tracer populations.
