We use the BCD spectrophotometric classification system to derive funda- mental parameters of B stars in NGC 2439, NGC 3766 and NGC 6087. We are able to perform a complete study of each open cluster by deriving spectral classification of its members, as well as the distance modulus and age. FULL TEXT IN SPANISH

Following specific criteria, we have carefully selected objects catalogued as galactic open cluster candidates. Out of a total of 58 small angular diameter selected objects without previous studies, we obtained integrated spectra of 18 of them at CASLEO (San Juan, Argentina). Using a computational tool specially developed for the analysis of integrated spectra, reddenings and ...
It is well known that open clusters are excellent tracers (in time and space) of the metallicity of the Galactic disk. We analyze the history of stellar for- mation of the Galactic disk using numerical simulations of the dynamical evolution of the open cluster system. We have included the effects of clus- ter disruption caused by stellar evolution, tidal ...
A new method is presented here to identify the members of an open cluster, based on computational taxonomy: "the spectral method". The characters used for the analysis are position and proper motion of all the stars belonging to the cluster's region. Numeric Taxonomy allows to groups the stars together in clusters, based on its genotypic characteristic, which shows the ...
Gamma-ray astronomy is opening the way to a universe far more energetic than anyone could have imagined half a century ago. The understanding of the processes of nature which carry a large portion of the energy in the universe, has astrophysical and cosmological implications. The next gen- eration of Cherenkov telescopes, an order of magnitude more sensitive and with higher ...
