      Context. The recent and exquisite astrometric, photometric, and radial velocity measurements of the Gaia mission resulted in a substantial advancement of the determination of the orbits for old star clusters, including the ...

    • The line-of-sight depth of populous clusters in the Small Magellanic Cloud 

      Crowl, Hugh H.; Sarajedini, Ata; Piatti, Andres E.; Geisler, Doug; Bica, Eduardo Luiz Damiani; Claria Olmedo, Juan Jose; Santos Junior, Joao Francisco Coelho dos (2001) [Artículo de periódico]
      We present an analysis of age, metal abundance, and positional data on populous clusters in the Small Magellanic Cloud (SMC) with the ultimate aim of determining the line-of-sight (LOS) depth of the SMC by using these ...

    • 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) [Artículo 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 ...
