The mass of a star is the most fundamental parameter for its structure, evolution, and final
fate. It is particularly important for any kind of stellar archaeology and characterization of …

The mantra “know thy star, know thy planet” has proven to be very important for many
aspects of exoplanet science. Here I review how stellar abundances inform our …

We present an empirical model of age-dependent photospheric lithium depletion, calibrated
using a large homogeneously analysed sample of 6200 stars in 52 open clusters, with ages …

Context. Transport processes occurring in the radiative interior of solar-type stars are
evidenced by the surface variation of light elements, in particular 7 Li, and the evolution of …

The main goal of this work is to evaluate the correlation between Li abundance, age, and
mass. Using high-quality ESO/HARPS data (R≃ 115 000; 270≤ SNR≤ 1000), we …

Context. Asteroseismology provides a unique opportunity to probe the interiors of evolved
stars and constrain their internal rotation. The correct reproduction of the core rotation …

Solar twins are stars of key importance to the field of astronomy and offer a multitude of
science applications. Only a small number (≲ 200) of solar twins are known today, all of …

Planet engulfment has been identified as one of the mechanisms for enhancing lithium
abundance in stars. However, comprehensive investigations into lithium signatures …

Context. Turbulent convection models treat stellar convection more physically than standard
mixing-length theory by including non-local effects. We recently successfully applied the …

Context. Exploring the Galactic chemical evolution and enrichment scenarios with open
clusters (OCs) allows us to understand the history of the Milky Way disk. High-resolution …
