Thorium in solar twins: implications for habitability in rocky planets
Rafael B. Botelho, Andre de C. Milone, Jorge Melendez +10
We have investigated the thorium (Th) abundance in a sample of 53 thin disc solar twins covering a wide range of ages. These data provide constrains on the mantle energy budget of…
The Solar Twin Planet Search: The age - chromospheric activity relation
Diego Lorenzo-Oliveira, Fabrício C. Freitas, Jorge Meléndez +8
It is well known that the magnetic activity of solar type stars decreases with age, but it is widely debated in the literature whether there is a smooth decline or if there is an e…
Lithium abundance patterns of late-F stars: an in-depth analysis of the lithium desert
Claudia Aguilera-Gómez, Iván Ramírez, Julio Chanamé
We address the existence and origin of the lithium (Li) desert, a region in the Li - T_eff plane sparsely populated by stars. Here we analyze some of the explanations that have bee…
Detailed chemical compositions of the wide binary HD 80606/80607: revised stellar properties and constraints on planet formation
F. Liu, D. Yong, M. Asplund +5
Differences in the elemental abundances of planet hosting stars in binary systems can give important clues and constraints about planet formation and evolution. In this study we pe…
