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...

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), 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., …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), 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.

Fryer, C. L., Timmes, F., Hungerford, A. L., Couture, A., Adams, F., Aoki, W., …Pignatari, M. (2019). Catching element formation in the act

Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects and phenomena: stars, supernovae, novae, neutron stars, stellar-mass b... Read More about Catching element formation in the act.
