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 ...
S1242: a lithium-rich subgiant star in the open cluster M 67
(Astronomy & Astrophysics, 2006-05-04)
The inhomogeneous submillimeter atmosphere of Betelgeuse
(EDP Sciences, 2017)
The mechanisms responsible for heating the extended atmospheres of early-M spectral-type supergiants are poorly understood. So too is the subsequent role these mechanisms play in driving the large mass-loss rates of these ...
A detailed study of lithium in 107 CHEPS dwarf stars
(EDP Sciences, 2018)
Context. We report results from lithium abundance determinations using high resolution spectral analysis of the 107 metal-rich stars from the Calan-Hertfordshire Extrasolar Planet Search programme.
Aims. We aim to set ...
