The power spectrum of ~630 days of full-disk solar velocity data, provided by the GOLF spectrophotometer aboard SOHO, has revealed the presence of mode-like structure well beyond the acoustic cut-off frequency for the solar atmosphere (nuac ~5.4 mHz). This kind of structure has already been observed in intermediate and high spatial resolution

A combination of inverse and forward analysis techniques has been applied to p-modes rotational splittings in order to infer the solar rotation rate in the deeper radiative regions (r 0.45Rodot). In this analysis, we first infer the rotation distribution down to 0.45Rodot using a 2D inversion method. We then use that rotation rate to discuss the

We have developed an efficient and accurate set of mostly analytic formulae, that describe the evolution of stars in a wide range of mass and metallicity from the zero-age main sequence to the tip of the AGB. These formulae are based on interpolation between full detailed stellar models. A particular advantage of this kind of algorithm, compared
