Basic parameters of three star clusters in the Small Magellanic Cloud: Kron 11, Kron 63 and NGC 121
G. Baume, N. E. D. Noël, E. Costa +3
We present observations for three star clusters, Kron 11, Kron 63 and NGC 121, in the Small Magellanic Cloud. We have studied their structure and derived their fundamental paramete…
Spiral structure in the outer Galactic disk. I. The Third Galactic Quadrant
Ruben A. Vazquez, Jorge May, Giovanni Carraro +3
We combine optical and radio observations to trace the spiral structure in the Third Quadrant of the Milky Way. The optical observations consist of a large sample of young open clu…
The anticenter old open cluster NGC 1883: radial velocity and metallicity
Sandro Villanova, Gustavo Baume, Giovanni Carraro
Having already reported on the first photometric study of the intermediate-age open cluster NGC 1883 (Carraro et al. 2003), we present in this paper the first spectroscopic multi-e…
The extended star formation history of the star cluster NGC 2154 in the Large Magellanic Cloud
Gustavo Baume, Giovanni Carraro, Edgardo Costa +2
The color-magnitude diagram (CMD) of the intermediate-age Large Magellanic Cloud (LMC) star cluster NGC 2154 and its adjacent field, has been analyzed using Padova stellar models t…
Photometry of a Galactic field at l = 232, b = -6. The old open cluster Auner 1, the Norma-Cygnus spiral arm and the signature of the warped Galactic Thick Disk
Giovanni Carraro, Andre' Moitinho, Manuela Zoccali +2
We perform a detailed photometric study of the stellar populations in a Galactic Field at l = 232, b = -6 in the Canis Major (CMa) constellation. We present the first U,B,V,I photo…
Spiral structure of the Third Galactic Quadrant and the solution to the Canis Major debate
A. Moitinho, R. A. Vazquez, G. Carraro +3
With the discovery of the Sagittarius dwarf spheroidal (Ibata et al. 1994), a galaxy caught in the process of merging with the Milky Way, the hunt for other such accretion events h…
