Solar twins in M 67: evolutionary status and lithium abundance
(EDP SCIENCES S A, 2011)
Aims. We determine the age and mass of the three best solar twin candidates in open cluster M 67 through lithium evolutionary models. Methods. We computed a grid of evolutionary models with non-standard mixing at metallicity ...

Masses, oxygen, and carbon abundances in CHEPS dwarf stars
(EDP Sciences, 2019)
Context. We report the results from the determination of stellar masses, carbon, and oxygen abundances in the atmospheres of 107 stars from the Calan-Hertfordshire Extrasolar Planet Search (CHEPS) programme. Our stars are ...
The metal-rich abundance pattern - spectroscopic properties and abundances for 107 main-sequence stars
(Oxford university press, 2017)
We report results from the high-resolution spectral analysis of the 107 metal-rich (mostly [Fe/H] >= 7.67 dex) target stars from the Calan Hertfordshire Extrasolar Planet Search programme observed with HARPS. Using our ...
Rotation periods and ages of solar analogs and solar twins revealed by the kepler mission
(The American Astronomical Society, 2014-08-01)
A new sample of solar analogs and twin candidates has been constructed and studied, paying particular attention to their light curves from NASA’s Kepler mission. This Letter aims to assess their evolutionary status, derive ...
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 ...
Rotation periods and ages of solar analogs and solar twins revealed by the kepler mission

Mass effect on the lithium abundance evolution of open clusters: Hyades, NGC 752, and M67
(EDP Sciences, 2016-03-12)
Lithium abundances in open clusters provide an e ective way of probing mixing processes in the interior of solar-type stars and convection is not the only mixing mechanism at work. To understand which mixing mechanisms are ...
