"On Solar Siblings and Solar Twins"
Earlier this year we identified a star that was likely born in the cluster where the Sun formed. I will briefly talk about the work that led to that discovery and how well it was received by the general public. Then I will talk about my research on solar twin stars, in particular the extreme levels of high precision that we have been able to achieve in determining their atmospheric parameters and elemental abundances. The latter have allowed us to uncover intriguing abundance patterns that can be interpreted as chemical signatures of planet formation.
