The observations of Li abundances in pre-Main-Sequence, Main-Séquence (Population I
and II), sub-giant, and giant stars are reviewed in order to show how Li can be used as a …

The Relation between Rotational Velocities and Spectral Peculiarities among A-Ty ADS Classic
is now deprecated. It will be completely retired in October 2019. This page will automatically …

Stellar evolution models of stars of 1.45–3.0 M⊙ have been calculated, including the atomic
diffusion of metals and radiative accelerations for all species in the OPAL opacities. As the …

With a combination of adaptive optics imaging and a multi-epoch common proper motion
search, we have conducted a large volume-limited (D≤ 75 pc) multiplicity survey of A-type …

Atomic diffusion is a fundamental physical process. Its universal presence is not questioned.
Yet, in stellar astrophysics it is often abusively ignored. Arguments that it plays a negligible …

We present the results of three-dimensional simulations of core convection within A-type
stars of 2 M☉, at a range of rotation rates. We consider the inner 30% by radius of such …

The lithium abundance gap in the Hyades F stars - The signature of diffusion ADS Classic is now
deprecated. It will be completely retired in October 2019. This page will automatically redirect to …

The last few decades have seen significant progress in our understanding of the occurrence
of magnetic fields in stars with radiative envelopes, in particular in massive stars and in …

Consistent stellar evolution models of F stars (1.1–1.5 M &sun;) are calculated with radiative
forces, opacities, and diffusion for all elements included in OPAL's opacity tables. The …

Some arguments about the role of lithium abundances in constraining evolutionary
processes in halo stars are discussed. Attention is given to the recent observations of Spite …
