Star Cluster Systems in Interacting and Starburst Galaxies: A Multicolour Approach
Richard de Grijs
The large majority of extragalactic star cluster studies done to date have essentially used two or three-passband aperture photometry, combined with theoretical stellar population…
Mass segregation in rich clusters in the Large Magellanic Cloud - III. Implications for the initial mass function
R. de Grijs, G. F. Gilmore, A. D. Mackey +4
The distribution of core radii of rich clusters in the Large Magellanic Cloud (LMC) systematically increases in both upper limit and spread with increasing cluster age. Cluster-to-…
Analysis of colour-magnitude diagrams of rich LMC clusters: NGC 1831
L. O. Kerber, B. X. Santiago, R. Castro +1
We present the analysis of a deep colour-magnitude diagram (CMD) of NGC 1831, a rich star cluster in the LMC. The data were obtained with HST/WFPC2 in the F555W (~V) and F814W (~I)…
On the nature of a secondary main sequence turn-off in the rich LMC cluster NGC 1868
B. Santiago, L. Kerber, R. Castro +1
Evidence for a second main-sequence turn-off in a deep colour-magnitude diagram of NGC 1868 is presented. The data were obtained with HST/WFPC2 and reach down to m_{555} ~ 25. Besi…
An HST Survey of the mid-UV Morphology of Nearby Galaxies
R. A. Windhorst, V. A. Taylor, R. A. Jansen +12
(Abbreviated) We present an imaging survey of 37 nearby galaxies observed with HST/WFPC2 in the mid-UV F300W filter and in F814W. 11 galaxies were also imaged in F255W. These galax…
Flattening and truncation of stellar discs in edge-on spiral galaxies
Michiel Kregel, Pieter C. van der Kruit, Richard de Grijs
We analyse the global structure of the old stellar discs in 34 edge-on spiral galaxies. The radial and vertical exponential scale parameters of the discs are obtained by applying a…
