• Deep colour-magnitude diagrams of LMC field stars imaged with HST 

      Castro, Rodrigo; Santiago, Basilio Xavier; Gilmore, Gerard Fitzgerald; Beaulieu, Sylvie F.; Johnson, Rachel A. (2001) [Artigo de periódico]
      We present deep photometry …V < ~26† in V and I bands obtained with the Wide Field and Planetary Camera 2 on board the Hubble Space Telescope for 7 fields ~5◦ away from the Large Magellanic Cloud centre. The fields contain, ...
    • Hst observations of the field star population in the large magellanic cloud 

      Elson, Rebecca A.W.; Gilmore, Gerard Fitzgerald; Santiago, Basilio Xavier (1997) [Artigo de periódico]
      We present V and I photometry, obtained with the Hubble Space Telescope, for ~ 15 800 stars in a field in the inner disc of the Large Magellanic Cloud. We confirm previous results indicating that an intense star formation ...
    • Mass segregation in young compact clusters in the Large Magellanic Cloud - III. Implications for the initial mass function 

      Grijs, Richard de; Gilmore, Gerard Fitzgerald; Mackey, Alasdair Dougal; Wilkinson, Mark I.; Beaulieu, Sylvie F.; Johnson, Rachel A.; Santiago, Basilio Xavier (2002) [Artigo de periódico]
      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-cluster variations in the stellar initial ...
    • Stellar luminosity functions of rich star clusters in the Large Magellanic Cloud 

      Santiago, Basilio Xavier; Beaulieu, Sylvie F.; Johnson, Rachel A.; Gilmore, Gerard Fitzgerald (2001) [Artigo de periódico]
      We show the results of deep V and I HST photometry of 6 rich star clusters in the Large Magellanic Cloud with di erent ages and metallicities. The number of stars with measured magnitudes in each cluster varies from about ...
    • The Gaia-ESO survey : radial metallicity gradients and age-metallicity relation of stars in the Milky Way disk

      We study the relationship between age, metallicity, and α-enhancement of FGK stars in the Galactic disk. The results are based upon the analysis of high-resolution UVES spectra from the Gaia-ESO large stellar survey. We ...
    • The metal-rich globular cluster NGC 6553 : observations with WFPC2, STIS, and NICMOS 

      Beaulieu, Sylvie F.; Gilmore, Gerard Fitzgerald; Elson, Rebecca A.W.; Johnson, Rachel A.; Santiago, Basilio Xavier; Sigurdsson, Steinn; Tanvir, Nial R. (2001) [Artigo de periódico]
      We present a Hubble Space Telescope study of the metal-rich globular cluster NGC 6553 using WFPC2, NICMOS, and STIS. Our primary motivation is to calibrate the STIS broadband LP magnitude against V555 and I814 magnitudes ...
    • Two serendipitous low-mass lmc dusters discovered with hst 

      Santiago, Basilio Xavier; Elson, Rebecca A.W.; Sigurdsson, Steinn; Gilmore, Gerard Fitzgerald (1998) [Artigo de periódico]
      We present V and I photometry of two open clusters in the LMC down to V~26. The clusters were imaged with the Wide Field and Planetary Camera 2 (WFPC2) on board the Hubble Space Telescope (HST), as part of the Medium Deep ...
    • Young star clusters in the Large Magellanic Cloud : NGC 1805 and 1818 

      Johnson, Rachel A.; Beaulieu, Sylvie F.; Gilmore, Gerard Fitzgerald; Hurley, Jarrod; Santiago, Basilio Xavier; Tanvir, Nial R.; Elson, Rebecca A.W. (2001) [Artigo de periódico]
      We present colour-magnitude diagrams for two rich (~~104 M̛) Large Magellanic Cloud star clusters with ages ~~ 107 yr, constructed from optical and near-infrared data obtained with the Hubble Space Telescope. These data ...
