Stellar Clusters are very useful laboratories for empirically studying stellar evolution. ... All cluster stars are at the same distance . All cluster stars have the same physical age . ... CM diagram Young Cluster In this case we see the Main Sequence fully represented. The blue dots represent massive stars with short main sequence lifetimes. ... Thus, identifying the most massive star which is still on the main sequence is an effective means of determining the age of a stellar cluster. ...

News & Views There seems to be something very healthy about astronomical research when, under the same cover, an event which took place in 1333 AD (Leonid bursts as a resonance meteoroid component from Comet Temple/Tuttle) is discussed followed by a paper on how we might more effectively search for extraterrestrial intelligence (in the optical). In this issue we also have a further paper on young clusters (Praesepe) and the low end of the stellar mass function (see IAJ , 1999, 26(1), 17). ...

... The overall globular cluster population is divided by gap in the metallicity function at [Fe/H]=-1.0 into two discrete groups with well-defined maxima at [Fe/H]=-1.60?0.03 dex, and -0.60?0.04 dex. ... Clusters with extremely blue horizontal branches occupy a spherical volume of radius ~ 9 kpc, have high rotational velocities ( V rot =77?33 km/s), have substantial and equal negative radial and vertical metallicity gradients, and are, on average, the oldest group (the old-halo subsystem). ...
