Add to ORKGIn this work we present differential chemical abundances\ud of neutron-capture elements (Z >30) in solar\ud twins. We have obtained high resolution (R =\ud 60,000) and high S/N ( >100) spectra of solar twins\ud in the ultraviolet region (310-400nm) with the UVES\ud spectrograph at the VLT/ESO. In the same configuration\ud we also observed that the Sun, that is our\ud reference for the differential analysis, thus obtaining\ud results with high accuracy and precision. In the ultraviolet\ud there is a large number of atomic transitions\ud of heavy elements, which allows the detailed study\ud of the r and s processes. Our sample of solar twins\ud covers a wide range of ages, so it will be possible to\ud study the temporal evolution of the neutr...
