APOGEE CHEMICAL TAGGING CONSTRAINT ON THE MAXIMUM STAR CLUSTER MASS IN THE alpha-ENHANCED GALACTIC DISK
Stars born from the same molecular cloud should be nearly homogeneous in their element abundances. The concept of chemical tagging is to identify members of disrupted clusters by their clustering in element abundance space. Chemical tagging requires large samples of stars with precise abundances for many individual elements. With uncertainties of σ[X/Fe] and σ[Fe/H] ≃ 0.05 for 10 elements measured for >104 stars, the APOGEE DR12 spectra may be the first well-suited data set to put this idea...[Show more]
