Abstract:
We continue our survey of magnetic chemically peculiar (CP2) stars in
galactic open clusters to shed more light on their origin and
evolution.
To study the group of CP2 stars, it is essential to find these objects
in different galactic environments and at a wide range of evolutionary
stages. The knowledge of open cluster ages and metallicities can help
for finding a correlation between these parameters and the
(non-)presence of peculiarities, which has to be taken into account in
stellar evolution models.
