VizieR Online Data Catalog: LAMOST DR4 New mercury-manganese stars (Paunzen+, 2021)
Abstract
Using an altered version of Richard O. Gray's MKCLASS code, which was tailored to probe several HgII and MnII features relevant to the identification of CP3 stars, we searched for CP3 stars among the LAMOST DR4 spectra of a colour-preselected sample of early-type stars. The spectra of all selected candidates were visually inspected; non-CP3 objects were sorted out and the strength of the HgII and MnII features was estimated. Depending on this estimate, the resulting sample was divided into bona fide CP3 stars, good CP3 star candidates, and candidates.
