Description
Novae are key sites of explosive nucleosynthesis, producing isotopes such as beryllium-7, which subsequently decays into lithium-7. This makes them strong candidates for explaining the observed Galactic lithium abundance, which exceeds theoretical predictions. In this work, I examine the potential impact of high-energy emission of secondary e+e- pairs produced along gamma-rays in hadronic interactions in expanding nova shells, on the 478 keV line associated with the decay of beryllium-7 to lithium-7. I also discuss observational prospects for novae detections with next-generation keV–MeV orbital observatories.
