Benchmark ages for the Gaia benchmark stars

Christian L. Sahlholdt, Sofia Feltzing, Lennart Lindegren +1

In the era of large-scale surveys of stars in the Milky Way, stellar ages are crucial for studying the evolution of the Galaxy. But determining ages of field stars is notoriously d…

The Gaia-ESO Survey: properties of newly discovered Li-rich giants

R. Smiljanic, E. Franciosini, A. Bragaglia +41

We report 20 new lithium-rich giants discovered within the Gaia-ESO Survey, including the first Li-rich giant with evolutionary stage confirmed by CoRoT data. Atmospheric parameter…

Stellar multiplicity in high-resolution spectroscopic surveys. I. Application to APOGEE subgiants and giants

Edita Stonkutė, Ross P. Church, Sofia Feltzing +1

Many field stars reside in binaries, and the analysis and interpretation of photometric and spectroscopic surveys must take this into account. We have developed a model to predict…

Estimating stellar ages and metallicities from parallaxes and broadband photometry - successes and shortcomings

Louise M. Howes, Lennart Lindegren, Sofia Feltzing +2

A deep understanding of the Milky Way galaxy, its formation and evolution requires observations of huge numbers of stars. Stellar photometry, therefore, provides an economical meth…

Detailed chemical compositions of the wide binary HD 80606/80607: revised stellar properties and constraints on planet formation

F. Liu, D. Yong, M. Asplund +5

Differences in the elemental abundances of planet hosting stars in binary systems can give important clues and constraints about planet formation and evolution. In this study we pe…
