Single-lined Spectroscopic Binary Star Candidates from a Combination of the RAVE and Gaia DR2 Surveys (2019)
Journal Article
Birko, D., Zwitter, T., Grebel, E. K., Parker, Q. A., Kordopatis, G., Bland-Hawthorn, J., Freeman, K., Guiglion, G., Gibson, B. K., Navarro, J., Reid, W., Seabroke, G. M., Steinmetz, M., & Watson, F. (in press). Single-lined Spectroscopic Binary Star Candidates from a Combination of the RAVE and Gaia DR2 Surveys. Astronomical Journal, 158(4), Article 155. https://doi.org/10.3847/1538-3881/ab3cc1

The combination of the final version of the Radial Velocity Experiment (RAVE) spectroscopic survey data release 6 with radial velocities (RVs) and astrometry from Gaia DR2 allows us to identify and create a catalog of single-lined binary star candida...

(2019). 2D-Galactic chemical evolution: The role of the spiral density wave. Monthly notices of the Royal Astronomical Society, 490(1), 665-682. https://doi.org/10.1093/mnras/stz2537

© 2019 The Author(s). Published by Oxford University Press on behalf of the Royal Astronomical Society. We present a 2D chemical evolution code applied to a Milky Way type Galaxy, incorporating the role of spiral arms in shaping azimuthal abundance v...

Galactic chemical evolution of radioactive isotopes (2019)
Journal Article
Côté, B., Lugaro, M., Reifarth, R., Pignatari, M., Világos, B., Yagüe, A., & Gibson, B. K. (2019). Galactic chemical evolution of radioactive isotopes. The Astrophysical journal, 878(2), Article 156. https://doi.org/10.3847/1538-4357/ab21d1

The presence of short-lived (∼ Myr) radioactive isotopes in meteoritic inclusions at the time of their formation represents a unique opportunity to study the circumstances that led to the formation of the Solar System. To interpret these observations... Read More about Galactic chemical evolution of radioactive isotopes.

The R-Process Alliance: Discovery of a Low-α, r-process-enhanced Metal-poor Star in the Galactic Halo (2019)
Journal Article
Wyse, R. F., Sakari, C. M., Roederer, I. U., Placco, V. M., Beers, T. C., Ezzeddine, R., Frebel, A., Hansen, T., Sneden, C., Cowan, J. J., Wallerstein, G., Farrell, E. M., Venn, K. A., Matijevič, G., Wyse, R. F. G., Bland-Hawthorn, J., Chiappini, C., Freeman, K. C., Gibson, B. K., Grebel, E. K., …Watson, F. (2019). The R-Process Alliance: Discovery of a Low-α, r-process-enhanced Metal-poor Star in the Galactic Halo. The Astrophysical journal, 874(2), Article 148. https://doi.org/10.3847/1538-4357/ab0c02

A new moderately r-process-enhanced metal-poor star, RAVE J093730.5−062655, has been identified in the Milky Way halo as part of an ongoing survey by the R-Process Alliance. The temperature and surface gravity indicate that J0937−0626 is likely a hor... Read More about The R-Process Alliance: Discovery of a Low-α, r-process-enhanced Metal-poor Star in the Galactic Halo.

Impact of observational selection functions on simulated age and metallicity distributions (2019)
Thesis
Atkin, D. (2019). Impact of observational selection functions on simulated age and metallicity distributions. (Thesis). University of Hull. Retrieved from https://hull-repository.worktribe.com/output/4222148

I use a novel approach to close the gap between observations and simulations of stellar abundance and ages by comparing observational data from Gaia-ESO 4th release (GES-iDR4) with that of a Milky Way-like galaxy simulation. The simulation is brought... Read More about Impact of observational selection functions on simulated age and metallicity distributions.
