Indirect Measurement of the Mg Direct Capture Reaction Rate via (He,d) Spectroscopy
Kaixin Song, Richard Longland, Caleb Marshall +3
The cross section of the reaction is dominated by direct capture at low energies relevant for stellar burning. Such cross sections can be constr…
High Resolution Study of Ca to Constrain Potassium Nucleosynthesis in NGC 2419
William Fox, Richard Longland, Caleb Marshall +1
The globular cluster NGC 2419 was the first to exhibit a Mg-K anticorrelation, linked to hydrogen burning at temperatures between 80-260 MK. However, the key K-destroying reaction,…
New Constraints on Sodium Production in Globular Clusters From the NaHeMg Reaction
C. Marshall, K. Setoodehnia, G. C. Cinquegrana +4
The star to star anticorrelation of sodium and oxygen {is} a defining feature of globular clusters, but, to date, the astrophysical site responsible for this unique chemical signat…
The impact of O reaction rate uncertainties on the s-process in rotating massive stars
J. Frost-Schenk, P. Adsley, A. M. Laird +9
Massive stars are crucial to galactic chemical evolution for elements heavier than iron. Their contribution at early times in the evolution of the Universe, however, is unclear due…
A study of Cl excited states via S()
Kiana Setoodehnia, John H. Kelley, Caleb Marshall +2
Presolar grains originating in oxygen-neon novae may be identified by their sulfur isotopic ratios compared with theoretical estimates. These ratios depend on reliable S($p,…
Excited states of Ca and their significance in nova nucleosynthesis
Kiana Setoodehnia, Caleb Marshall, Richard Longland +3
Background: Discrepancies exist between the observed abundances of argon and calcium in oxygen-neon nova ejecta and those predicted by nova models. An improved characterization of…
