New Evidence of Binarity in Young α-Rich Turn-off and Subgiant Stars: Fast Rotation and Strong Magnetic Activity
Jie Yu, Luca Casagrande, Ioana Ciucă +3
Young α-rich (YAR) stars within the old Galactic thick disk exhibit a dual characteristic of relative youth determined with asteroseismology and abundance enhancement in α elements…

The vertical metallicity gradients of mono-age stellar populations in the Milky Way with the RAVE and Gaia data
Ioana Ciucă, Daisuke Kawata, Jane Lin +3
We investigate the vertical metallicity gradients of five mono-age stellar populations between 0 and 11 Gyr for a sample of 18 435 dwarf stars selected from the cross-matched Tycho…

Metallicity Gradient of the Thick Disc Progenitor at High Redshift
D. Kawata, C. Allende Prieto, C. B. Brook +6
We have developed a novel Markov Chain Mote Carlo (MCMC) chemical "painting" technique to explore possible radial and vertical metallicity gradients for the thick disc progenitor.…
