Double Horizontal Branches in NGC 6440 and NGC 6569 unveiled by the VVV Survey
Francesco Mauro, Christian Moni Bidin, Roger Cohen +5
We report the discovery of a peculiar horizontal branch (HB) in NGC 6440 and NGC 6569, two massive and metal-rich Galactic globular clusters (GGCs) located in the Galactic bulge, w…
Massive open star clusters using the VVV survey II. Discovery of six clusters with Wolf-Rayet stars
A. -N. Chené, J. Borissova, C. Bonatto +20
Context: The ESO Public Survey "VISTA Variables in the Vía Láctea" (VVV) provides deep multi-epoch infrared observations for an unprecedented 562 sq. degrees of the Galactic bulge,…
Spectroscopy of horizontal branch stars in Omega Centauri
C. Moni Bidin, S. Villanova, G. Piotto +3
We analyze the reddening, surface helium abundance and mass of 115 horizontal branch (HB) and blue hook (BH) stars in OmegaCentauri, spanning the HB from the blue edge of the insta…
Massive open star clusters using the VVV survey I. Presentation of the data and description of the approach
A. -N. Chené, J. Borissova, J. R. A. Clarke +15
Context: The ESO Public Survey "VISTA Variables in the Vía Láctea" (VVV) provides deep multi-epoch infrared observations for an unprecedented 562 sq. degrees of the Galactic bulge,…
Kinematical and chemical vertical structure of the Galactic thick disk II. A lack of dark matter in the solar neighborhood
C. Moni Bidin, G. Carraro, R. A. Mendez +1
We estimated the dynamical surface mass density Sigma at the solar position between Z=1.5 and 4 kpc from the Galactic plane, as inferred from the kinematics of thick disk stars. Th…
No evidence of dark matter in the solar neighborhood
C. Moni Bidin, G. Carraro, R. A. Mendez +1
We measured the surface mass density of the Galactic disk at the solar position, up to 4 kpc from the plane,by means of the kinematics of ~400 thick disk stars. The results match t…
