The escape speed curve of the Galaxy obtained from Gaia DR2 implies a heavy Milky Way
Giacomo Monari, Benoit Famaey, Ismael Carrillo +6
We measure the escape speed curve of the Milky Way based on the analysis of the velocity distribution of counter-rotating halo stars from the Gaia DR2. The distances we…
The metal-rich halo component extended in z: a characterization with Gaia DR2 and APOGEE
Emma Fernández-Alvar, J. G. Fernández-Trincado, Edmundo Moreno +12
We report an analysis of the metal-rich tail ([Fe/H] ) of halo stars located at distances from the Galactic plane up to kpc, observed by the Apache Point…
Spiral arm crossings inferred from ridges in Gaia stellar velocity distributions
Alice C. Quillen, Ismael Carrillo, Friedrich Anders +7
The solar neighborhood contains disc stars that have recently crossed spiral arms in the Galaxy. We propose that boundaries in local velocity distributions separate stars that have…
Estimating stellar birth radii and the time evolution of the Milky Way's ISM metallicity gradient
I. Minchev, F. Anders, A. Recio-Blanco +14
We present a semi-empirical, largely model-independent approach for estimating Galactic birth radii, r_birth, for Milky Way disk stars. The technique relies on the justifiable assu…
Chemo-kinematics of the Milky Way from the SDSS-III MARVELS Survey
Nolan Grieves, Jian Ge, Neil Thomas +20
Combining stellar atmospheric parameters, such as effective temperature, surface gravity, and metallicity, with barycentric radial velocity data provides insight into the chemo-dyn…
Dissecting stellar chemical abundance space with t-SNE
Friedrich Anders, Cristina Chiappini, Basílio X. Santiago +4
In the era of industrial Galactic astronomy and multi-object spectroscopic stellar surveys, the sample sizes and the number of available stellar chemical abundances have reached di…
