The intermediate age globular cluster NGC 152 in the Small MagellanicCloud.
Abstract
The color-magnitude diagram of the populous Small Magellanic Cloud cluster NGC 152, measured to V approximately equal to 22, shows that it has an age of about 8 x 10 to the 8th years and is moderately metals-deficient. Its giant branch is sparsely populated, but includes at least two carbon stars at very red colors. There is a richly populated clump of intermediate-color giants at MV approximately 0. Several superluminous giants are detected, also at intermediate colors, but averaging MV approximately -2.0. The C-M diagram for the nearby field has very similar properties to those of the cluster.
