Photoelectric search for CP2-stars in open clusters. XIII. NGC 3114 and IC 2602.
Abstract
Delta-a photometric observations of two open clusters, obtained using the 50-cm and 1-m telescopes at ESO during 1981-1984, are reported. The data are presented in extensive tables and graphs and briefly characterized. Of the 168 stars measured, eight (six in NGC 3114 and two in IC 2602) are identified as chemically peculiar upper-main-sequence objects with magnetic fields. These hot CP2 stars are found to be blueshifted relative to the cluster main sequences on the V/(b-y) diagrams.
