The effects of rotation on the lithium depletion of G- and K-dwarfs in Messier 35 (2020)
Journal Article
Jeffries, R. D., Jackson, R. J., Sun, Q., & Deliyannis, C. P. (2021). The effects of rotation on the lithium depletion of G- and K-dwarfs in Messier 35. Monthly Notices of the Royal Astronomical Society, 500(1), 1158-1177. https://doi.org/10.1093/mnras/staa3141

New fibre spectroscopy and radial velocities from the WIYN telescope are used to measure photospheric lithium in 242 high-probability, zero-age-main-sequence (ZAMS) F- to K-type members of the rich cluster M35. Combining these with published rotation... Read More about The effects of rotation on the lithium depletion of G- and K-dwarfs in Messier 35.

The Gaia-ESO Survey: Galactic evolution of lithium at high metallicity (2020)
Journal Article
Jeffries, R., & Wright, N. J. (2020). The Gaia-ESO Survey: Galactic evolution of lithium at high metallicity. Astronomy and Astrophysics, https://doi.org/10.1051/0004-6361/202038688

Context. Reconstructing the Galactic evolution of lithium (Li) is the main tool used to constrain the source(s) of Li enrichment in the Galaxy. Recent results have suggested a decline in Li at supersolar metallicities, which may indicate reduced prod... Read More about The Gaia-ESO Survey: Galactic evolution of lithium at high metallicity.

The Gaia-ESO survey: the non-universality of the age-chemical-clocks-metallicity relations in the Galactic disc (2020)
Journal Article
Jeffries. (2020). The Gaia-ESO survey: the non-universality of the age-chemical-clocks-metallicity relations in the Galactic disc. Astronomy & Astrophysics, https://doi.org/10.1051/0004-6361/202038055

Context. In the era of large spectroscopic surveys, massive databases of high-quality spectra coupled with the products of the Gaia satellite provide tools to outline a new picture of our Galaxy. In this framework, an important piece of information i... Read More about The Gaia-ESO survey: the non-universality of the age-chemical-clocks-metallicity relations in the Galactic disc.

The Gaia-ESO Survey: Membership probabilities for stars in 32 open clusters from 3D kinematics (2020)
Journal Article
Jeffries, & Wright. (2020). The Gaia-ESO Survey: Membership probabilities for stars in 32 open clusters from 3D kinematics. Monthly Notices of the Royal Astronomical Society, 4701-4716. https://doi.org/10.1093/mnras/staa1749

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 assign membership p...

The dynamics of the γ Vel cluster and nearby Vela OB2 association (2020)
Journal Article
Armstrong, J. J., Wright, N., Jeffries, R., & Jackson, R. J. (2020). The dynamics of the γ Vel cluster and nearby Vela OB2 association. Monthly Notices of the Royal Astronomical Society, 494(4), 4794 -4801. https://doi.org/10.1093/mnras/staa939

The kinematics of low-mass stars in nearby OB associations can provide clues about their origins and evolution. Combining the precise positions, proper motions, and parallaxes given in the second Gaia Data Release with radial-velocity measurements ob...

A kinematically hot population of young stars in the solar neighbourhood (2020)
Journal Article
Binks, A., Wright, N., & Jeffries, R. (2020). A kinematically hot population of young stars in the solar neighbourhood. Monthly Notices of the Royal Astronomical Society, 494(2), 2429-2439. https://doi.org/10.1093/mnras/staa909

In the last three decades several hundred nearby members of young stellar moving groups (MGs) have been identified, but there has been less systematic effort to quantify or characterise young stars that do not belong to previously identified MGs. Usi... Read More about A kinematically hot population of young stars in the solar neighbourhood.

The Gaia-ESO Survey: detection and characterisation of single-line spectroscopic binaries (2020)
Journal Article
Merle, T., Van der Swaelmen, M., Van Eck, S., Jorissen, A., Jackson, R. J., Traven, G., …Prisinzano, L. (2020). The Gaia-ESO Survey: detection and characterisation of single-line spectroscopic binaries. Astronomy & Astrophysics, 635, https://doi.org/10.1051/0004-6361/201935819

Context. Multiple stellar systems play a fundamental role in the formation and evolution of stellar populations in galaxies. Recent and ongoing large ground-based multi-object spectroscopic surveys significantly increase the sample of spectroscopic b...

The Gaia-ESO Survey: a new approach to chemically characterising young open clusters - I. Stellar parameters, and iron-peak, nd proton-capture elements (2020)
Journal Article

Context. Open clusters are recognised as excellent tracers of Galactic thin-disc properties. At variance with intermediate-age and old open clusters, for which a significant number of studies is now available, clusters younger than ?150 Myr have been...
