Constraints on the star formation history of the Large Magellanic Cloud
Javiel, Sandro Caldeira; Santiago, Basilio Xavier; Kerber, Leandro de Oliveira (2005) [Journal article]We present the analysis of deep colour–magnitude diagrams (CMDs) of 6 stellar fields in the LMC. The data were obtained using HST/WFPC2 in the F814W (∼I) and F555W (∼V) filters, reaching V555 ∼ 26.5.We discuss and apply a ... -
Constraints on thick disc and halo parameters from HST photometry of field stars in the Galaxy
Kerber, Leandro de Oliveira; Javiel, Sandro Caldeira; Santiago, Basilio Xavier (2001) [Journal article]We analyse a sample of over 1000 stars from 32 fields imaged in the V and I bands with the Wide Field and Planetary Camera, on board of the Hubble Space Telescope. The fields are located at Galactic latitudes |b| ≥ 15º and ... -
Multiband photometry towards the inner galactic bulge : extinction, atmospheric parameters, and metallicities
Santiago, Basilio Xavier; Javiel, Sandro Caldeira; Mello, Gustavo Frederico Porto de (2006) [Journal article]Context. We have obtained BVRI photometry for 21 stellar fields located in directions towards the central 3.5° of the Galaxy. Each field is 10 × 10 arcmin in size, and a total of ∼2 × 105 stars were measured.
