Title: | Chemo-dynamical signatures in simulated Milky Way-like galaxies | Authors: | SPAGNA, Alessandro CURIR, Anna GIAMMARIA, MARCO LATTANZI, Mario Gilberto MURANTE, Giuseppe RE FIORENTIN, Paola |
Issue Date: | 2018 | Volume: | Astrometry and Astrophysics in the Gaia Sky | Editors: | Recio-Blanco, Alejandra; de Laverny, Patrick; Brown, Anthony G. A.; Prusti, Timo | Series: | PROCEEDINGS OF THE INTERNATIONAL ASTRONOMICAL UNION | Number: | 330 | First Page: | 263 | Abstract: | We have investigated the chemo-dynamical evolution of a Milky Way-like disk galaxy, AqC4, produced by a cosmological simulation integrating a sub-resolution ISM model. We evidence a global inside-out and upside-down disk evolution, that is consistent with a scenario where the ``thin disk'' stars are formed from the accreted gas close to the galactic plane, while the older ``thick disk'' stars are originated in situ at higher heights. Also, the bar appears the most effective heating mechanism in the inner disk. Finally, no significant metallicity-rotation correlation has been observed, in spite of the presence of a negative [Fe/H] radial gradient. | Conference Name: | Astrometry and Astrophysics in the Gaia sky | Conference Place: | Nice, France | Conference Date: | 24-28 April, 2017 | URI: | http://hdl.handle.net/20.500.12386/28202 | URL: | https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/chemodynamical-signatures-in-simulated-milky-waylike-galaxies/3DA716984D646CB6F9511BAE936532EA | ISSN: | 1743-9213 | ISBN: | 9781107170087 | DOI: | 10.1017/S1743921317006019 | Bibcode ADS: | 2018IAUS..330..263S | Fulltext: | open |
