Description

Photoelectric and photographic measures of 183 stars in the field of NGC 2439 show the cluster to be approx.2times107 years old and 4.45 kpc from the Sun. Three supergiant stars, including the G0 Ia star R Puppis, are found to be very probable memebers on the basis of photometric, spectral, and radial-velocity data. An extended group of high-luminosity B stars may also be associated with the cluster
