Learn about groundbreaking research exploring the origin of one of the most metal-poor stars ever detected in a 22-minute lecture presented by Pilar Gil Pons from UPC, Spain. Dive into the study of carbon-enhanced extremely metal-poor (CEMP) stars and their crucial role in understanding the Universe's first stars. Examine the unique abundance pattern of HE 1327-2326, featuring high CNO patterns, light element variations, and the presence of Sr and Ba. Follow the investigation comparing yield abundances of intermediate-mass primitive star models using stellar structure evolution and nucleosynthetic postprocessing codes. Discover how this research challenges previous theories by suggesting intermediate-mass stars, rather than just high-mass supernovae, may have played a significant role in early universe pollution and the formation of hyper metal-poor stars.
