Hidden Companions of the Early Milky Way I. New alpha-Enhanced Exoplanet Hosts

This article announces the discovery of new exoplanet hosts with high alpha-element abundances, suggesting they formed in the early Milky Way. The research likely focuses on characterizing these stars and their planetary systems to understand the chemical evolution of the galaxy and the conditions for planet formation in its early stages. The title indicates this is the first in a series of papers.
