A BCool magnetic snapshot survey of solar-type stars
We present the results of a major high-resolution spectropolarimetric BCool project magnetic survey of 170 solar-type stars. Surface magnetic fields were detected on 67 stars, with 21 classified asExpand

Detection of a weak surface magnetic field on Sirius A: are all tepid stars magnetic?
Aims. We aim at a highly sensitive search for weak magnetic fields in main sequence stars of intermediate mass, by scanning classes of stars with no previously reported magnetic members. AfterExpand

The Liège Oscillation code
Abstract The Liège Oscillation code can be used as a stand-alone program or as a library of subroutines that the user calls from a Fortran main program of his own to compute radial and nonradialExpand

Lithium in M 67: From the main sequence to the red giant branch
Lithium abundances in open clusters are a very effective probe of mixing processes, and their study can help to understand the large depletion of lithium in the Sun. Due to its age and metallicity,Expand

Age and mass of solar twins constrained by lithium abundance
Aims. We analyze the non-standard mixing history of the solar twins HIP 55 459, HIP 79 672, HIP 56 948, HIP 73 815, and HIP 100 963, to determine as precisely as possible their mass and age. Methods.Expand

The radius and mass of the close solar twin 18 Scorpii derived from asteroseismology and interferometry
The growing interest in solar twins is motivated by the possibility of comparing them directly to the Sun. To carry on this kind of analysis, we need to know their physical characteristics withExpand
