Oxygen and silicon abundances in Cygnus OB2. Chemical homogeneity in a sample of OB slow rotators
Context. Cygnus OB2 is a rich OB association in the Galaxy located at only ˜1.4 kpc from us which has experienced intense star formation in the last 20-25 Myr. Its stellar population shows a correlation between age and Galactic longitude. Exploring the chemical composition of its stellar content we will be able to check the degree of homogeneity of
