Discovery of a thin lithium plateau among metal-poor red giant branch stars
A. Mucciarelli, L. Monaco, P. Bonifacio +5
The surface lithium abundance A(Li) of warm metal-poor dwarf stars exhibits a narrow plateau down to [Fe/H]~-2.8 dex, while at lower metallicities the average value drops by 0.3 de…
Thorough characterisation of the 16 Cygni system. Part II. Seismic inversions of the internal structure
G. Buldgen, M. Farnir, P. Eggenberger +5
The advent of space-based photometry observations provided high-quality asteroseismic data for a large number of stars. These observations enabled the adaptation of advanced techni…
Atomic diffusion in solar-like stars with MESA. Comparison with the Montreal/Montpellier and CESTAM stellar evolution codes
Bernardo Campilho, Morgan Deal, Diego Bossini
The stellar evolution code Modules for Experiments in Stellar Astrophysics (MESA) is public and is widely used by the community. It includes the possibility of taking several non-s…
Primordial nucleosynthesis with varying fundamental constants: Solutions to the Lithium problem and the Deuterium discrepancy
M. Deal, C. J. A. P. Martins
The success of primordial nucleosynthesis has been limited by the long-standing Lithium problem. We use a self-consistent perturbative analysis of the effects of relevant theoretic…
Fundamental properties of a selected sample of Ap stars: Inferences from interferometric and asteroseismic constraints
M. Deal, M. S. Cunha, Z. Keszthelyi +2
Magnetic fields influence the formation and evolution of stars and impact the observed stellar properties. Ap stars (magnetic A-type stars) are a prime example of this. Access to p…
Matter accretion in metal-poor stars down to extremely metal-poor stars and the lithium problem
M. Deal, O. Richard, S. Vauclair
The formation and evolution of light elements in the Universe act as important cosmological constraints. It has long been assumed that the oldest stars of the Galaxy display the pr…
