Low-mass, helium-enriched PG1159 stars: a possible evolutionary origin and the implications for their pulsational stability properties
(EDP Sciences, 2007-12)
Aims. We examine a recently-proposed evolutionary scenario that could explain the existence of the low-mass, helium-enriched PG 1159 stars. We focus in particular on studying the pulsational stability properties of the ...

Lithium abundances and rotational behavior for bright giant stars
(EDP Sciences, 2005-11-16)
Aims.We study the links possibly existing between the lithium content of bright giant stars and their rotational velocity. Methods.We performed a spectral analysis of 145 bright giant stars (luminosity class II) spanning ...
