Solar Twins and Their Implications for Planets, Stars and the Galaxy

Explore the fascinating research on solar twins and their significant implications for planets, stars, and galactic studies in this lecture by Jorge Luiz Meléndez Moreno from IAG, USP. Presented as part of the ICTP-SAIFR São Paulo Research Group meetings in Astro & Cosmo on March 17, 2025, the talk delves into how solar twins—stars nearly identical to our Sun—provide crucial insights for understanding planetary formation, stellar evolution, and galactic development. Discover how these stellar doppelgangers serve as important reference points in astronomical research and what they reveal about our cosmic neighborhood.
