The Pleiades Architecture
Rapid advances in portable computing and communication devices require implementations that must not only be highly energy efficient, but they must also be flexible enough to support a variety of multimedia services and communication capabilities. The required flexibility dictates the use of programmable processors in implementing the increasingly sophisticated digital signal processing algorit...
متن کاملInvestigation of the Pleiades cluster ⋆
On the basis of the best available member list and duplicity information, we have studied the radial distribution of 270 stars and multiple systems earlier than K0 in the Pleiades. Five new long period spectroscopic binaries have been identified from the CORAVEL observations. We have found a clear mass segregation between binaries and single stars, which is explained by the greater average mass...

متن کاملStatistics of binaries in the Pleiades cluster
We present a statistical analysis of binaries in galactic clusters, based on photometric properties. Synthetic clusters are used to solve the deconvolution problem. If the colourmagnitude relation for single stars is given and if triple stars are treated as binaries, the distribution of systems in a colourmagnitude diagram (CMD) can be used to determine cluster properties. They include the maxi...
متن کاملThe Pleiades mass function : models versus observations
Two stellar-dynamical models of binary-rich embedded proto-Orion-Nebula-type clusters that evolve to Pleiades-like clusters are studied with an emphasis on comparing the stellar mass function with observational constraints. By the age of the Pleiades (about 100 Myr) both models show a similar degree of mass segregation which also agrees with observational constraints. This thus indicates that t...
