Abundances in the Milky Way across Five Nucleosynthetic Channels from 4 Million LAMOST Stars
Abundances in the Milky Way across Five Nucleosynthetic Channels from 4 Million LAMOST Stars
Abstract Large stellar surveys are revealing the chemodynamical structure of the Galaxy across a vast spatial extent. However, the many millions of low-resolution spectra observed to date are yet to be fully exploited. We employ The Cannon , a data-driven approach for estimating chemical abundances, to obtain detailed abundances from …
