Chemical abundances in seven red giants of NGC 2360 and NGC 2447
S. Hamdani, P. North, N. Mowlavi +2
Chemical abundances of about fifteen elements from oxygen to europium are measured in seven red giants of the two open clusters NGC 2360 and NGC 2447. The effective temperatures of…
Evolution of mass segregation in open clusters: some observational evidences
D. Raboud, J. -C. Mermilliod
On the basis of the best available member list and duplicity information, we have studied the radial structure of Praesepe and of the very young open cluster NGC 6231. We have foun…
Mass segregation in very young open clusters
D. Raboud
The study of the very young open cluster NGC 6231 clearly shows the presence of a mass segregation for the most massive stars. These observations, combined with those concerning ot…
Investigation of the Pleiades cluster. IV. The radial structure
D. Raboud, J. -C. Mermilliod
On the basis of the best available member list and duplicity information, we have studied the radial distribution of 270 stars and multiple systems earlier than K0 in the Pleiades.…
