A revised age greater than 50 Myr for the young cluster IC 4665 (2023)
Journal Article
Jeffries, R. D., Jackson, R. J., & Binks, A. S. (2023). A revised age greater than 50 Myr for the young cluster IC 4665. Monthly Notices of the Royal Astronomical Society, 526(1), 1260-1267. https://doi.org/10.1093/mnras/stad2845

IC 4665 is one of only a dozen young open clusters with a “lithium depletion boundary” (LDB) age. Using an astrometrically and spectroscopically filtered sample of cluster members, we show that both the positions of its low mass stars in Gaia absolut...

The Gaia-ESO Survey: Homogenisation of stellar parameters and elemental abundances (2023)
Journal Article
Hourihane, A., François, P., Worley, C. C., Magrini, L., Gonneau, A., Casey, A. R., …Minkevičiūtė, R. (2023). The Gaia-ESO Survey: Homogenisation of stellar parameters and elemental abundances. Astronomy & Astrophysics, 676, Article A129. https://doi.org/10.1051/0004-6361/202345910

The Gaia-ESO Survey is a public spectroscopic survey that targeted greater than or similar to 10(5) stars covering all major components of the Milky Way from the end of 2011 to 2018, delivering its final public release in May 2022. Unlike other spect... Read More about The Gaia-ESO Survey: Homogenisation of stellar parameters and elemental abundances.

The Gaia-ESO Survey: empirical estimates of stellar ages from lithium equivalent widths (eagles) (2023)
Journal Article
Jeffries, R. D., Jackson, R. J., Wright, N. J., Weaver, G., Gilmore, G., Randich, S., …Zaggia, S. (2023). The Gaia-ESO Survey: empirical estimates of stellar ages from lithium equivalent widths (eagles). Monthly Notices of the Royal Astronomical Society, 523(1), 802-824. https://doi.org/10.1093/mnras/stad1293

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 to 6000 Myr and -0.3 < [Fe/H] < 0.2, observed in the Gaia-ESO sp...

Mapping the distribution of OB stars and associations in Auriga (2023)
Journal Article
Quintana, A. L., Wright, N. J., & Jeffries, R. D. (2023). Mapping the distribution of OB stars and associations in Auriga. Monthly Notices of the Royal Astronomical Society, 522(2), 3124-3137. https://doi.org/10.1093/mnras/stad1160

OB associations are important probes of recent star formation and Galactic structure. In this study, we focus on the Auriga constellation, an important region of star formation due to its numerous young stars, star-forming regions, and open clusters....

The Gaia-ESO Survey: Preparing the ground for 4MOST and WEAVE galactic surveys (2023)
Journal Article
Nepal, S., Guiglion, G., de Jong, R., Valentini, M., Chiappini, C., Steinmetz, M., …Zaggia, S. (2023). The Gaia-ESO Survey: Preparing the ground for 4MOST and WEAVE galactic surveys. Astronomy & Astrophysics, 671, Article A61. https://doi.org/10.1051/0004-6361/202244765

Context. Originating from several sources (Big Bang, stars, cosmic rays) and being strongly depleted during stellar lifetime, the lithium element is of great interest as its chemical evolution in the Milky Way is not yet well understood. To help cons... Read More about The Gaia-ESO Survey: Preparing the ground for 4MOST and WEAVE galactic surveys.
