Low-extinction windows in the inner Galactic Bulge
We built K band extinction maps in the area of two candidate low-extinction windows in the inner Bulge: W0.2-2.1 at (l,b) = (0.25o,-2.15o), and W359.4-3.1 at (l,b) = (359.40o,-3.10o). We employedExpand

Stellar luminosity functions of rich star clusters in the Large Magellanic Cloud
We show the results of deep V and I HST photometry of 6 rich star clusters in the Large Magellanic Cloud with different ages and metallicities. The number of stars with measured magnitudes in eachExpand

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 massExpand

On the nature of a secondary main-sequence turn-off in the rich LMC cluster NGC 1868
Evidence for a second main-sequence turn-off in a deep colour‐magnitude diagram (CMD) of NGC 1868 is presented. The data were obtained with Hubble Space Telescope (HST) WFPC2 and reach down to m555 �Expand
