Mass segregation in rich LMC clusters from modelling of deep HST colour–magnitude diagrams
Aims. We used the deep colour–magnitude diagrams (CMDs) of five rich LMC clusters (NGC 1805, NGC 1818, NGC 1831, NGC 1868, and Hodge 14) observed with HST/WFPC2 to derive their present day mass function (PDMF) and its variation with position within the cluster. Methods. The PDMF was parameterized as a power law in the available main-sequence mass range of each cluster, typically 0.9 <∼ m/M <∼ 2...
متن کاملPhysical parameters of 15 intermediate - age LMC clusters from modelling of HST colour - magnitude diagrams
Aims. We analyzed HST/WFPC2 colour-magnitude diagrams (CMDs) of 15 populous Large Magellanic Cloud (LMC) stellar clusters with ages between ∼ 0.3 Gyr and ∼ 3 Gyr. These (V, B-V) CMDs are photometrically homogeneous and typically reach V∼22. Accurate and self-consistent physical parameters (age, metallicity, distance modulus and reddening) were extracted for each cluster by comparing the observe...
متن کاملStar Formation Histories from HST Color-Magnitude Diagrams of Six Fields of the LMC
We present results on the analysis of background field stars found in HST WFPC2 observations of six of the old globular clusters of the Large Magellanic Cloud. Treated as contaminants by the globular cluster analysts, we produce V − I, V color-magnitude diagrams of the field stars and use them to explore the LMC’s star formation history. The photometry approaches V ∼ 26, well below the turnoff ...
متن کاملOn the self-consistent physical parameters of LMC intermediate-age clusters
The LMC clusters with similar ages to the Milky Way open clusters are in general more metal-poor and more populous than the latter, being located close enough to allow their stellar content to be well resolved. Therefore, they are unique templates of simple stellar population (SSP), being crucial to calibrate models describing the integral light as well as to test the stellar evolution theory. ...
متن کاملwoman-defined identity: analysis of selected poems of adrienne rich
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
