Chemical evolution of fluorine in the Milky Way (2022)
Journal Article
Womack, K., Vincenzo, F., Gibson, B., Côté, B., Pignatari, M., Brinkman, H. E., Ventura, P., & Karakas, A. (2023). Chemical evolution of fluorine in the Milky Way. Monthly notices of the Royal Astronomical Society, 518(1), 1543-1556. https://doi.org/10.1093/mnras/stac3180

Fluorine has many different potential sites and channels of production, making narrowing down a dominant site of fluorine production particularly challenging. In this work, we investigate which sources are the dominant contributors to the galactic fl... Read More about Chemical evolution of fluorine in the Milky Way.

Journal of Physics G: Nuclear and Particle Physics, 49(11), Article 110502. https://doi.org/10.1088/1361-6471/ac8890

Nuclear astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the chemical elements. This white paper summarizes progress and status of... Read More about Horizons: nuclear astrophysics in the 2020s and beyond.

The NuGrid AGB Evolution and Nucleosynthesis Data Set (2022)
Journal Article
Battino, U., Pignatari, M., Tattersall, A., Denissenkov, P., & Herwig, F. (2022). The NuGrid AGB Evolution and Nucleosynthesis Data Set. Universe, 8(3), Article 170. https://doi.org/10.3390/universe8030170

Asymptotic Giant Branch (AGB) stars play a key role in the chemical evolution of galaxies. These stars are the fundamental stellar site for the production of light elements such as C, N and F, and half of the elements heavier than Fe via the slow neu...

A Large-scale Approach to Modeling Molecular Biosignatures: The Diatomics (2022)
Journal Article
Cross, T. M., Benoit, D. M., Pignatari, M., & Gibson, B. K. (2022). A Large-scale Approach to Modeling Molecular Biosignatures: The Diatomics. The Astrophysical journal, 925(1), Article 57. https://doi.org/10.3847/1538-4357/ac3976

This work presents the first steps to modeling synthetic rovibrational spectra for all molecules of astrophysical interest using a new approach implemented in the Prometheus code. The goal is to create a new comprehensive source of first-principles m... Read More about A Large-scale Approach to Modeling Molecular Biosignatures: The Diatomics.

Galactic Chemical Evolution of Radioactive Isotopes with an s-process Contribution (2022)
Journal Article
Trueman, T. C. L., Côté, B., Yagüe López, A., Den Hartogh, J., Pignatari, M., Soós, B., Karakas, A. I., & Lugaro, M. (2022). Galactic Chemical Evolution of Radioactive Isotopes with an s-process Contribution. The Astrophysical journal, 924(1), 10. https://doi.org/10.3847/1538-4357/ac31b0

Analysis of inclusions in primitive meteorites reveals that several short-lived radionuclides (SLRs) with half-lives of 0.1-100 Myr existed in the early solar system (ESS). We investigate the ESS origin of 107Pd, 135Cs, and 182Hf, which are produced... Read More about Galactic Chemical Evolution of Radioactive Isotopes with an s-process Contribution.
