Enrichment of the Galactic disc with neutron capture elements: Sr (2019)
Journal Article
Mishenina, T., Pignatari, M., Gorbaneva, T., Bisterzo, S., Travaglio, C., Thielemann, F. K., & Soubiran, C. (2019). Enrichment of the Galactic disc with neutron capture elements: Sr. Monthly notices of the Royal Astronomical Society, 484(3), 3846-3864. https://doi.org/10.1093/mnras/stz178The enrichment history of heavy neutron-capture elements in the Milky Way disc provides fundamental information about the chemical evolution of our Galaxy and about the stellar sources that made those elements. In this work we give new observational... Read More about Enrichment of the Galactic disc with neutron capture elements: Sr.

Remnants and ejecta of thermonuclear electron-capture supernovae: Constraining oxygen-neon deflagrations in high-density white dwarfs (2018)
Journal Article
Jones, S., Röpke, F. K., Fryer, C., Ruiter, A. J., Seitenzahl, I. R., Nittler, L. R., Ohlmann, S. T., Reifarth, R., Pignatari, M., & Belczynski, K. (2019).

The s process in AGB stars as constrained by a large sample of barium stars (2018)
Journal Article
Cseh, B., Lugaro, M., D'Orazi, V., de Castro, D. B., Pereira, C. B., Karakas, A. I., Molnár, L., Plachy, E., Szabó, R., Pignatari, M., & Cristallo, S. (2018).

Barium (Ba) stars are dwarf and giant stars enriched in elements heavier than iron produced by the slow neutron-capture process (s process). These stars belong to binary systems in which the primary star evolved through the asymp... Read More about The s process in AGB stars as constrained by a large sample of barium stars.
