Exploring the orbits of the stars via chemical tagging techniques

Borja Anguiano (Macquarie University, Australia)

Using the chemical groups identified by Mitschang et al. 2013 on a local sample of around 700 stars observed with high-resolution spectroscopy, I will report some properties on the orbital parameters (Rmin, Rmax, eccentricity, Zmax, angular momentum, orbital energy) and their temporal evolution and how we can use this information for understanding the radial migration theory in a real disk. I will also mention the GALAH survey where this kind of studies will be possible for a sample 1000 times larger thanks to the synergies with Gaia.
