Unveiling the nature of HE 0107-5240
E. Caffau, M. Steffen, P. Molaro +27
The vast majority of the most iron-poor stars in the Galaxy exhibit a strong carbon enhancement, with C/H ratios only about two orders of magnitude below solar. This unusual chemic…
A Sequoia stellar candidate with very high 7Li and 9Be
L. Monaco, E. Caffau, P. Molaro +2
Aims. The metal-poor star BPM 3066 belongs to the retrograde halo and presents unexpectedly strong spectral features of lithium. To gain insight into the origin of this peculiar ab…
Possible evidence for the 478 keV emission line from Be decay during the outburst phases of V1369 Cen
L. Izzo, T. Siegert, P. Jean +4
After decades of uncertainty about the origin of lithium, recent evidence suggests Galactic novae as its main astrophysical source. In this work, we present possible evidence for t…
Explaining the ratio in the Galactic halo: the contribution from shell mergers in primordial massive stars
F. Rizzuti, G. Cescutti, P. Molaro +5
Recent campaigns of observations have provided new measurements of the carbon isotopes in the most metal-poor stars of the Galaxy. These stars are so metal-poor that they could onl…
