A catalog of rotational and radial velocities for evolved starsA catalog of rotational and radial velocities for evolved stars
(EDP Sciences, 2006-07-20)
Aims.The present paper describes the first results of an observational program intended to refine and extend the existing measurements of metal-poor stars, with an emphasis on field evolved stars. Methods.The survey was ...

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.

Gamma-ray emission from star-forming regions
(Società Astronomica Italiana, 2010-04)
Star-forming regions have been tentatively associated with gamma-ray sources since the early days of the COS B satellite. After the many sources detected by the Compton Gamma-Ray Observatory, the statistical evidence for ...
On the incidence of chemically peculiar stars in the Large Magellanic Cloud
(Oxford University Press, 2005-09)
With the aim to corroborate the result of a search for chemically peculiar stars in the Large Magellanic Cloud (LMC), we present measurements obtained from CCD imaging of two fields, one containing a young open cluster ...
Entropy, complexity and disequilibrium in compact stars
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We used the statistical measurements of information entropy, disequilibrium and complexity to infer a hierarchy of equations of state for two types of compact stars from the broad class of neutron stars, namely, with ...
