The frequency of metal enrichment of cool helium-atmosphere white dwarfs using the DESI early data release (2024)
Journal Article
Manser, C. J., Gänsicke, B. T., Izquierdo, P., Swan, A., Najita, J., Rockosi, C., …Zou, H. (2024). The frequency of metal enrichment of cool helium-atmosphere white dwarfs using the DESI early data release. Monthly Notices of the Royal Astronomical Society: Letters, 531(1), L27-L32. https://doi.org/10.1093/mnrasl/slae026

There is an overwhelming evidence that white dwarfs host planetary systems; revealed by the presence, disruption, and accretion of planetary bodies. A lower limit on the frequency of white dwarfs that host planetary material has been estimated to be...

The individual abundance distributions of disc stars across birth radii in GALAH (2023)
Journal Article
Carrillo, A., Ness, M. K., Wang, K., & Buck, T. (2024). The individual abundance distributions of disc stars across birth radii in GALAH. Monthly Notices of the Royal Astronomical Society, 527(1), Article 321–333. https://doi.org/10.1093/mnras/stad3182

Individual abundances in the Milky Way disc record stellar birth properties [e.g. age, birth radius (Rbirth)], and capture the
diversity of the star-forming environments over time. Assuming an analytical relationship between ([Fe/H], [α/Fe]), and Rb... Read More about The individual abundance distributions of disc stars across birth radii in GALAH.

The Relationship between Age, Metallicity, and Abundances for Disk Stars in a Simulated Milky Way (2023)
Journal Article
Carrillo, A., Ness, M. K., Hawkins, K., Sanderson, R. E., Wang, K., Wetzel, A., & Bellardini, M. A. (2023). The Relationship between Age, Metallicity, and Abundances for Disk Stars in a Simulated Milky Way. Astrophysical Journal, 942(1), Article 35. https://doi.org/10.3847/1538-4357/aca1c7

Observations of the Milky Way's low-α disk show that several element abundances correlate with age at fixed metallicity, with unique slopes and small scatters around the age–[X/Fe] relations. In this study, we turn to simulations to explore the age–[... Read More about The Relationship between Age, Metallicity, and Abundances for Disk Stars in a Simulated Milky Way.

The detailed chemical abundance patterns of accreted halo stars from the optical to infrared (2022)
Journal Article
Carrillo, A., Hawkins, K., Jofré, P., de Brito Silva, D., Das, P., & Lucey, M. (2022). The detailed chemical abundance patterns of accreted halo stars from the optical to infrared. Monthly Notices of the Royal Astronomical Society, 513(2), 1557-1580. https://doi.org/10.1093/mnras/stac518

Understanding the assembly of our Galaxy requires us to also characterize the systems that helped build it. In this work, we accomplish this by exploring the chemistry of accreted halo stars from Gaia-Enceladus/Gaia-Sausage (GES) selected in the infr...
