Issue Date: | 2018 | Volume: | Rediscovering Our Galaxy | Editors: | Chiappini, C.; Minchev, I.; Starkenburg, E.; Valentini, M. | Series: | PROCEEDINGS OF THE INTERNATIONAL ASTRONOMICAL UNION | Number: | 334 | First Page: | 86 | Abstract: | The four main findings about the age and abundance structure of the Milky Way bulge based on microlensed dwarf and subgiant stars are: (1) a wide metallicity distribution with distinct peaks at [Fe/H] = -1.09, -0.63, -0.20, +0.12, +0.41; (2) a high fraction of intermediate-age to young stars where at [Fe/H] > 0 more than 35 % are younger than 8 Gyr, (3) several episodes of significant star formation in the bulge 3, 6, 8, and 11 Gyr ago; (4) the `knee' in the α-element abundance trends of the sub-solar metallicity bulge appears to be located at a slightly higher [Fe/H] (about 0.05 to 0.1 dex) than in the local thick disk. | Conference Name: | Rediscovering Our Galaxy | Conference Place: | Potsdam, Germany | Conference Date: | 10-14 July, 2017 | URI: | http://hdl.handle.net/20.500.12386/30461 | URL: | https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/age-and-abundance-structure-of-the-stellar-populations-in-the-central-subkpc-of-the-milky-way/CCBE7FE63592073DFB10E8B9028028D0 | ISSN: | 1743-9213 | ISBN: | 978-1-107-19234-8 | DOI: | 10.1017/S1743921317007426 | Bibcode ADS: | 2018IAUS..334...86B | Fulltext: | open |
