generalization of star-mesh transformation
it is well know that any three impedances or admittances connected into each other in a star form can be easily transformed to a new three impedances or admittances connected into each other in a mesh form. in this paper a generalization of this fact is established and it is shown that in an n + 1 node network which is connected in a form it is always possible to eliminate the center node and o...
متن کاملBinary Star Measurements with the Star re
Four binaries, 10 UMa, UMa, 81 Cnc, and UMa, were observed with adaptive optics on the 3.5m telescope at the Starrre Optical Range on March 24, 1998, in order to investigate the relative photometry produced by adaptive optics within the isoplanatic patch. Iterative Blind Deconvolution (IBD) and Parametric Blind Deconvolution (PBD) techniques were used to post-process the data, and produced cons...
متن کاملMassive Star and Star Cluster Formation
I review the status of massive star formation theories: accretion from collapsing, massive, turbulent cores; competitive accretion; and stellar collisions. I conclude the observational and theoretical evidence favors the first of these models. I then discuss: the initial conditions of star cluster formation as traced by infrared dark clouds; the cluster formation timescale; and comparison of th...
متن کاملStar formation in galaxies and star clusters
This thesis is devoted to star formation from galaxy-scales (≈ 10 000 pc) to sub-star cluster-scales (≈ 0.1 pc). I develop and test a new method to derive star formation histories of Galaxies from their star cluster content, in particular the most massive star clusters. This is followed by an application of this method to the Large Magellanic Cloud, where the results of this new method are conf...
متن کاملStar Formation Efficiencies and Star Cluster Formation
Starbursts produce large numbers of Young Star Clusters (YSCs). Multi-color photometry in combination with a dedicated SED analysis tool allows to derive ages, metallicities, EB−V, and masses including 1σ uncertainties for individual clusters and, hence, mass functions for YSC systems. The mass function, known to be Gaussian for old Globular Cluster (GC) systems, is still controversial for YSC ...
