Lithium Abundance in Pop.II Stars A post-HIPPARCOS discussion

Spite, M.; Hill, V.; Spite, F.

The relation between the lithium abundance observed in Population II stars and the primordial abundance, is still an open question (see Cayrel and Duncan, this meeting). A few recent results are discussed. HIPPARCOS data show that the standard model of stellar evolution can explain the 6Li detection in HD 84937, suggesting a negligible depletion o…

Sensitivity of Low Frequency Oscillations to Updated Solar Models

Provost, J.; Berthomieu, G.; Morel, P.

A large number of acoustic frequencies have already been detected, leading to a "seismic" model of the Sun rather close to the actual standard solar models. The core however is not yet well constrained by these observations and frequencies of low degree, low frequency modes which penetrate deeply into the solar core are needed. We present here a s…

Galactic Evolution of the Light Elements: A New Set of B Observations

Primas, F.

The boron 2500 Angstroms spectral region has been observed with the Goddard High Resolution Spectrograph (GHRS) of the Hubble Space Telescope (HST) in a new set of metal-poor stars and analyzed by spectrum synthesis technique, adopting the most recent model atmospheres. By taking into account the Li and Be abundances available from the literature …
