DOI: 10.1093/mnras/staa1749
Abstract: The Gaia-ESO Survey (GES) observed many open clusters as part of its programme to spectroscopically characterise the various Milky Way populations. GES spectroscopy and Gaia astrometry from its second data release are used here to… read more here.

DOI: 10.1093/mnras/stad1293
Abstract: We present an empirical model of age-dependent photospheric lithium depletion, calibrated using a large, homogeneously-analysed sample of 6200 stars in 52 open clusters, with ages from 2–6000 Myr and −0.3 < [Fe/H] < 0.2, observed in… read more here.

DOI: 10.1093/mnras/stad1577
Abstract: We investigate the origin of neutron-capture elements by analyzing their abundance patterns and radial gradients in the Galactic thin disc. We adopt a detailed two-infall chemical evolution model for the Milky Way, including state-of-the-art nucleosynthesis… read more here.

DOI: 10.1093/mnras/stx2316
Abstract: The typical methodology for comparing simulated galaxies with observational surveys is usually to apply a spatial selection to the simulation to mimic the region of interest covered by a comparable observational survey sample. In this… read more here.

DOI: 10.1093/mnras/stz870
Abstract: The combination of precise radial velocities from multi-object spectroscopy and highly accurate proper motions from Gaia DR2 opens up the possibility for detailed 3D kinematic studies of young star forming regions and clusters. Here, we… read more here.
