Journal ArticleDOI
The age structure of stellar populations in the solar vicinity Clues of a two-phase formation history of the Milky Way disk
TL;DR: In this article, the authors analyzed a sample of solar neighborhood stars that have high-quality abundance determinations and showed that there are two distinct regimes of [α/Fe] versus age, which they identify as the epochs of the thick and thin disk formation.
Journal ArticleDOI
Gaia-2MASS 3D maps of Galactic interstellar dust within 3 kpc
Rosine Lallement,C. Babusiaux,C. Babusiaux,J. L. Vergely,David Katz,Frédéric Arenou,B. Valette,C. Hottier,L. Capitanio +8 more
TL;DR: In this paper, a hierarchical inversion algorithm was applied to the individual extinctions of stars in the Local Arm and surrounding regions to derive extinction toward stars that possess accurate photometry and relative uncertainties on DR2 parallaxes smaller than 20%.
Journal ArticleDOI
New grids of ATLAS9 atmospheres I: Influence of convection treatments on model structure and on observable quantities
Ulrike Heiter,Ulrike Heiter,Friedrich Kupka,C. van 't Veer-Menneret,C. Barban,Werner W. Weiss,M. J. Goupil,Wolfram Schmidt,David Katz,R. Garrido +9 more
TL;DR: In this article, the authors present several new sets of grids of model stellar atmospheres computed with modified versions of the ATLAS9 code, which are used for pulsation mode identification.
Journal ArticleDOI
The dominant epoch of star formation in the milky way formed the thick disk
O. Snaith,O. Snaith,Misha Haywood,Paola Di Matteo,Matthew D. Lehnert,Francoise Combes,David Katz,Ana Gomez +7 more
TL;DR: In this paper, the authors report the first robust measurement of the Milky Way star formation history using the imprint left on chemical abundances of long-lived stars, suggesting a fundamental role of this component in the genesis of our Galaxy, something that had been largely unrecognized.
Journal ArticleDOI
The dominant epoch of star formation in the Milky Way formed the thick disc
Owain Snaith,Misha Haywood,Paola Di Matteo,Matthew D. Lehnert,Francoise Combes,David Katz,Ana Gomez +6 more
TL;DR: In this article, the authors report the first robust measurement of the Milky Way star formation history using the imprint left on chemical abundances of long-lived stars, which implies that the thick disc is as massive as the thin disc, suggesting a fundamental role of this component in the genesis of our Galaxy.
