Two-component galaxies with flat rotation curve
Luca Ciotti, Lucia Morganti, Tim de Zeeuw
Dynamical properties of two-component galaxy models whose stellar density distribution is described by a gamma-model while the total density distribution has a pure r^(-2) profile,…
Abundances of four open clusters from solar stars
G. Pace, L. Pasquini, P. François
We present the abundance measurements of several elements (Fe, Ca, Na, Ni, Ti, Al, Cr, Si) for 20 solar--type stars belonging to four Galactic open clusters: NGC 3680, IC 4651, Pra…
Ground-based CCD astrometry with wide field imagers. II. A star catalogue for M67: [email protected] MPG/ESO astrometry, FLAMES@VLT radial velocities
R. K. S. Yadav, L. R. Bedin, G. Piotto +7
The solar-age open cluster M67 (C0847+120, NGC2682) is a touchstone in studies of the old Galactic disk. Despite its outstanding role, the census of cluster membership for M67 at f…
Mass-sheet degeneracy: Fundamental limit on the cluster mass reconstruction from statistical (weak) lensing
M. Bradac, M. Lombardi, P. Schneider
Weak gravitational lensing is considered to be one of the most powerful tools to study the mass and the mass distribution of galaxy clusters. However, weak lensing mass reconstruct…
Stellar Abundances in Giant Stars in the Metal-Rich Globular Cluster NGC6528
Sofia Feltzing, Francesca Primas, Rachel Johnson
We present the first results of a detailed abundance analysis, based on VLT observations, of giant stars in the very metal-rich globular cluster NGC 6528. We will be able to tie th…
