A search for radius inflation among active M-dwarfs in Praesepe (2018)
Journal Article
Jackson, R. J., Jeffries, R. D., Deliyannis, C. P., Sun, Q., & Douglas, S. T. (2019). A search for radius inflation among active M-dwarfs in Praesepe. Monthly Notices of the Royal Astronomical Society, 483(1), 1125-1138. https://doi.org/10.1093/mnras/sty3184

Rotation periods from Kepler K2 are combined with projected rotation velocities from the WIYN 3.5-m telescope, to determine projected radii for fast-rotating, low-mass ($0.15 \leq M/M_{\odot} \leq 0.6$) members of the Praesepe cluster. A maximum like... Read More about A search for radius inflation among active M-dwarfs in Praesepe.

The Gaia-ESO Survey: the origin and evolution of s-process elements (2018)

Jeffries. (2018). The Gaia-ESO Survey: the origin and evolution of s-process elements. Astronomy & Astrophysics, https://doi.org/10.1051/0004-6361/201832841

Context. Several works have found an increase of the abundances of the s-process neutron-capture elements in the youngest Galactic stellar populations. These trends provide important constraints on stellar and Galactic evolution and they need to be c... Read More about The Gaia-ESO Survey: the origin and evolution of s-process elements.

The Gaia DR2 view of the Gamma Velorum cluster: resolving the 6D structure (2018)
Journal Article
Franciosini, E., Sacco, G., Jeffries, R., Damiani, F., Roccatagliata, V., Fedele, D., & Randich, S. (2018). The Gaia DR2 view of the Gamma Velorum cluster: resolving the 6D structure. Astronomy & Astrophysics, 616, L12. https://doi.org/10.1051/0004-6361/201833815

Gaia-ESO Survey observations of the young Gamma Velorum cluster led to the discovery of two kinematically distinct populations, Gamma Vel A and B, respectively, with population B extended over several square degrees in the Vela OB2 association. Using... Read More about The Gaia DR2 view of the Gamma Velorum cluster: resolving the 6D structure.

The low mass population of the Vela OB2 association from Gaia (2018)
Journal Article

The first Gaia Data Release presents an opportunity to characterise the low-mass population of OB associations, providing larger statistical samples and better constraints on the formation and evolution of clusters and associations. Using previously... Read More about The low mass population of the Vela OB2 association from Gaia.

The Gaia-ESO Survey: a kinematical and dynamical study of four young open clusters (2018)
Journal Article

Context The origin and dynamical evolution of star clusters is an important topic in stellar astrophysics. Several models have been proposed in order to understand the formation of bound and unbound clusters and their evolution, and they can be test...

Context Determination and calibration of the ages of stars, which heavily rely on stellar evolutionary models, are very challenging, while representing a crucial aspect in many astrophysical areas. Aims We describe the methodologies that, taking... Read More about The Gaia-ESO Survey: open clusters in Gaia-DR1. A way forward to stellar age calibration.
