Asymmetric metallicity patterns in the stellar velocity space with RAVE
Asymmetric metallicity patterns in the stellar velocity space with RAVE
We explore the correlations between velocity and metallicity and the possible distinct chemical signatures of the velocity over-densities of the local Galactic neighbourhood. We use the large spectroscopic survey RAVE and the Geneva Copenhagen Survey. We compare the metallicity distribution of regions in the velocity plane ($v_R,v_ϕ$) with that of …
