| dc.description.abstractEn | A large dataset of ~2800 spectra extracted from the ELODIE archive was analysed in order to find solar twins. Stellar spectra closely resembling the spectrum of the Sun were selected by applying a purely differential method, directly on the fluxes. As solar reference, 18 spectra of asteroids, Moon, and blue sky were used. Atmospheric parameters and differential abundances of eight chemical elements were determined for the solar twin candidates after a careful selection of appropriate lines. The Li feature of the targets was investigated and additional information on absolute magnitude and age was gathered from the literature. HIP 076114 (HD 138573) is our best twin candidate; it looks exactly like the Sun in all these properties.Based on data extracted from the ELODIE archive at Observatoire de Haute-Provence (OHP), http://atlas.obs-hp.fr/elodie/Tables 2 and 4-8 are only available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (ftp://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/587/A131 | |
