NGC 2401: A template of the Norma-Cygnus Arm's young population in the Third Galactic Quadrant
G. Baume, A. Moitinho, R. Vazquez +3
Based on a deep optical CCD (UBV(RI)_C) photometric survey and on the Two-Micron All-Sky-Survey (2MASS) data we derived the main parameters of the open cluster NGC 2401. We found t…
uvby-βphotometry of high-velocity and metal-poor stars XI. Ages of halo and old disk stars
W. J. Schuster, A. Moitinho, A. Marquez +2
New uvby-βdata are provided for 442 high-velocity and metal-poor stars; 90 of these stars have been observed previously by us, and 352 are new. When combined with our previous two…
Open clusters in the Third Galactic Quadrant. II. The intermediate age open clusters NGC 2425 and NGC 2635
A. Moitinho, G. Carraro, G. Baume +1
We analyse CCD broad band (UBV(RI)c) photometric data obtained in the fields of the poorly studied open clusters NGC 2425 and NGC 2635. Both clusters are found to be of intermediat…
Detection of a young stellar population in the background of open clusters in the Third Galactic Quadrant
Giovanni Carraro, Ruben Vazquez, Andre Moitinho +1
We report the detection of a young stellar population (100 Myrs) in the ba ckground of 9 young open clusters belonging to a homogenoeous sample of 30 star clusters in the Thi…
A photometric study of the old open clusters Berkeley 73, Berkeley 75 and Berkeley 25
G. Carraro, D. Geisler, A. Moitinho +2
CCD BVI photometry of the faint open clusters Berkeley~73, Berkeley~75 and Berkeley~25 are presented. The two latter are previously unstudied clusters to our knowledge. While Berke…
The intermediate-age open clusters Ruprecht 4, Ruprecht 7 and Pismis 15
Giovanni Carraro, Doug Geisler, Gustavo Baume +2
We report on CCD photometry to for 3 fields centered on the region of the Galactic star clusters Ruprecht~4, Ruprecht~7 and Pismis~15 and on 3 displaced control fiel…
