Photoelectric search for CP2-stars in open clusters. X. NGC 2232, NGC2343, CR 140, and TR 10.
Abstract
One hundred stars in the regions of the four open clusters NGC 2232, NGC 2343, Cr 140, and Tr 10 were measured in the Delta(a)-system (Maitzen, 1976) in order to detect photometric peculiarity indicating CP2-stars. Of the total of 63 cluster member and probable member stars, only one turned out to be photometrically peculiar (NGC 2232-9), while Cr 140-60 is peculiar, but most likely a nonmember. Tr 10-19, a spectroscopically peculiar star according to one source (in disagreement with another), appears to be normal in the present observations.
