Abundance analysis of 5 early - type stars in the young open cluster IC 2391 ⋆


Aims. It is unclear whether chemically peculiar stars of the upper main sequence represent a class completely distinct from normal A-type stars, or whether there exists a continuous transition from the normal to the most peculiar late F-to early B-type stars. A systematic abundance analysis of open cluster early-type stars would help to relate the observed… (More)
