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…
On the difference between nuclear and contraction ages
W. Lyra, A. Moitinho, N. van der Bliek +1
Context:Ages derived from the low mass stars still contracting onto the main sequence often differ from ages derived from the high mass ones that have already evolved away from it.…
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…
