The Role of Massive Agb Stars in the Early Solar System Composition
Josep M. Trigo-Rodriguez, Domingo Anibal Garcia-Hernandez, Maria Lugaro +4
We demonstrate that a massive asymptotic giant branch (AGB) star is a good candidate as the main source of short-lived radionuclides in the early solar system. Recent identificatio…
The impact of the 18F(a,p)21Ne reaction on fluorine production in AGB stars
Amanda I. Karakas, Hye Young Lee, Maria Lugaro +2
The recent experimental evaluation of the 18F(a,p)21Ne reaction rate, when considering its associated uncertainties, presented significant differences compared to the theoretical H…
Blue Stragglers After the Main Sequence
Alison Sills, Amanda Karakas, John Lattanzio
We study the post-main sequence evolution of products of collisions between main sequence stars (blue stragglers), with particular interest paid to the horizontal branch and asympt…
Heavy element abundances in giant stars of the globular clusters M4 and M5
David Yong, Amanda I. Karakas, David L. Lambert +2
We present a comprehensive abundance analysis of 27 heavy elements in bright giant stars of the globular clusters M4 and M5 based on high resolution, high signal-to-noise ratio spe…
Chemical abundances in giants stars of the tidally disrupted globular cluster NGC 6712 from high-resolution infrared spectroscopy
David Yong, Jorge Melendez, Katia Cunha +3
We present abundances of C, N, O, F, Na, and Fe in six giant stars of the tidally disrupted globular cluster NGC 6712. The abundances were derived by comparing synthetic spectra wi…
The impact of the 18F(a,p)21Ne reaction on asymptotic giant branch nucleosynthesis
Amanda Karakas, Hye Young Lee, Maria Lugaro +2
We present detailed models of low and intermediate-mass asymptotic giant branch (AGB) stars with and without the 18F(a,p)21Ne reaction included in the nuclear network, where the ra…
