The role of low-lying resonances for $^{10}$Be(p,$\alpha$) reaction rate and implications for the formation of the Solar System

Understand

Evidence for the presence of short-lived radioactive isotopes when the Solar System formed is preserved in meteorites, providing insights into the conditions at the birth of our Sun.

• A low-mass core-collapse supernova had been postulated as a candidate for the origin of $^{10}$Be, reinforcing the idea that a supernova triggered the formation of the Solar System.
• We present a detailed study of the production of $^{10}$Be by the $\nu$ process in supernovae, which is very sensitive to the reaction rate of the major destruction channel, $^{10}$Be(p,$\alpha$)$^{7}$Li.
• With data from recent nuclear experiments that show the presence of a resonant state in $^{11}$B at $\approx$~193 keV, we derive new values for the $^{10}$Be(p,$\alpha$)$^{7}$Li reaction rate which are significantly higher than previous estimates.
