The presence of specific short-lived radionuclides in meteorite samples suggests that the formation of our Solar System was triggered by a nearby supernova explosion. A recent study showed that low-mass supernovae can produce ¹⁰Be at a level compatible with meteorite data. However, the 0Be yield in supernovae is highly sensitive to the ¹⁰Be(p,α)⁷Li destruction reaction. We studied the impact of this reaction on the ¹⁰Be yield from supernovae considering a recently observed near-threshold resonance in ¹¹B. Learn more
