Ages and metallicities of star clusters and surrounding fiels in the outer disk of the Large Magellanic Cloud
(1998) [Artículo de periódico]We present Washington system CT1 color-magnitude diagrams of 13 star clusters and their surrounding fields that lie in the outer parts of the LMC disk (r>4°), as well as a comparison inner cluster. The total area covered ... -
NGC 1912 and NGC 1907 : a close encounter between open clusters?
(2002) [Artículo de periódico]The possible physical relation between the closely projected open clusters NGC 1912 (M 38) and NGC 1907 is investigated. Previous studies suggested a physical pair based on similar distances, and the present study explores ... -
A photometric and spectroscopic study of the southern open clusters Pismis 18, Pismis 19, NGC 6005, and NGC 6253
(1998) [Artículo de periódico]CCD observations in the B, V , and I passbands have been used to generate color-magnitude diagrams (CMDs) for the southern open cluster candidates Pismis 18, Pismis 19, and NGC 6005, as well as for the old open cluster NGC ... -
A revised and extended catalog of Magellanic System clusters, associations, and emission nebulae. II. The Large Magellanic Cloud
(1999) [Artículo de periódico]A survey of extended objects in the Large Magellanic Cloud was carried out on the ESO/SERC R and J Sky Survey Atlases, checking entries in previous catalogs and searching for new objects. The census provided 6659 objects ... -
Statistics of stellar populations of star clusters and surrounding fields in the outer disk of the Large Magallanic Cloud
(1999) [Artículo de periódico]A comparative analysis of Washington color-magnitude diagrams (CMDs) for 14 star clusters and respective surrounding fields in the Large Magellanic Cloud (LMC) outer disk is presented. Each CCD frame including field and ... -
Updating the census of star clusters in the Small Magellanic Cloud
(2000) [Artículo de periódico]Surveys using CCD detectors are retrieving bright and faint cataloged clusters and revealing new ones in the Magellanic Clouds. This paper discusses the contribution of the OGLE Survey to the overall census of star clusters ...
