The old open cluster NGC 2112: updated estimates of fundamental parameters based on a membership analysis
Giovanni Carraro, Sandro Villanova, Pierre Demarque +2
We report on a new, wide field (), multicolor (), photometric campaign in the area of the nearby old open cluster NGC 2112. At the same time,…
Is a binary fraction-age relation responsible for the lack of EHB binaries in globular clusters?
C. Moni Bidin, M. Catelan, M. Altmann
The recently-discovered lack of close binaries, among extreme horizontal branch (EHB) stars in Galactic globular clusters, has thus far constituted a major puzzle, in view of the f…
The vertical velocity dispersion profile of the Galactic thick disk
C. Moni Bidin, T. M. Girard, G. Carraro +4
We present the results of radial velocity measurements of 770 thick disk red giants toward the South Galactic Pole, vertically distributed from 0.5 kpc to 5 kpc with respect to the…
Binaries among Extreme Horizontal Branch Stars in Globular Clusters
C. Moni Bidin, M. Catelan, S. Villanova +4
Following a review of our present knowledge about blue subdwarf stars in globular clusters, we present an overview of the results of searches for close binaries among these stars,…
A Search for EHB Pulsators in the Globular Cluster NGC 6752
M. Catelan, G. E. Prieto, M. Zoccali +8
We describe the status of a project whose main goal is to detect variability along the extreme horizontal branch of the globular cluster NGC 6752. Based on Magellan 6.5m data, prel…
Whiting 1: the youngest globular cluster associated with the Sgr dSph
Giovanni Carraro, Robert Zinn, Christian Moni Bidin
Recently, Carraro (2005) drew attention to the remarkable star cluster Whiting 1 by showing that it lies about 40 kpc from the Sun and is therefore unquestionably a member of the G…
