Chemo-orbital evidence from SDSS/SEGUE G dwarf stars for a mixed origin of the Galactic thick disk
About 13,000 G dwarf within 7<R<9kpc and 0.5<|z|<3.0 kpc from the SDSS/SEGUE spectroscopic survey are used to study the origin of the Milky Way thick disk. Combining [α/Fe] and [Fe/H] measurements with six-dimensional position-velocity parameters, we find that the sample is composed of t...
