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 ELT-MOS (MOSAIC): towards the construction phase

Simon Morris, François Hammer, Pascal Jagourel +50

When combined with the huge collecting area of the ELT, MOSAIC will be the most effective and flexible Multi-Object Spectrograph (MOS) facility in the world, having both a high mul…

The Gaia-ESO Survey: the origin and evolution of s-process elements

L. Magrini, L. Spina, S. Randich +45

Several works have found an increase of the abundances of the s-process neutron-capture elements in the youngest Galactic stellar populations, giving important constraints to stell…

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…
