Unraveling the cosmological Li problem - the discrepancy between Big Bang nucleosynthesis predictions and observed values in the Spite plateau - requires a comprehensive exploration of stellar evolution. In this study, we utilized the code STAREVOL t

Asteroseismology provides a unique opportunity to probe the interiors of evolved stars and constrain their internal rotation. The correct reproduction of the core rotation evolution is key to understanding the internal processes involved in low-mass

Open clusters provide clues to understand the evolution of Li7 at the surface of low-mass stars and its possible correlation with stellar rotation, which is a challenge for both stellar hydrodynamics and Galactic chemical evolution. We aim to quantif

Using topological notions of translation-like actions introduced by Schneider, we give a positive answer to a geometric version of Burnside problem for locally compact group. The main theorem states that a locally compact group is non-compact if and

Using explicit methods, we provide an upper bound to the norm of the Busemann cocycle of a locally finite regular tree $X$, emphasizing the symmetries of the cocycle. The latter takes value into a submodule of square summable functions on the edges o

In recent years, new experimental determinations of numerous nuclear reaction rates relevant for astrophysics have been achieved via direct and indirect experimental methods, highlighting specific trends like the unexpected fusion hindrance phenomeno

Robust modelling of low-mass stars is key to understand their structure and their evolution. So far, no clear consensus appears for which physics is required to reproduce the main observables: the evolution of chemicals (e.g. lithium, beryllium), the

We analyse the dispersion of Li in the atmosphere of 56 solar type stars including 22 solar twins. Lithium abundances are derived by comparing observed and synthetic spectra in the region of Li I line 6707 A, taking into account NLTE corrections. We

Transport processes occurring in the radiative interior of solar-type stars and low-mass stars are evidenced by the surface variation of light elements, in particular lithium (Li) and beryllium (Be), as well as by the evolution of the stellar rotatio
