The Gaia-ESO Survey: membership probabilities for stars in 32 open clusters from 3D kinematics
(Royal Astronomical Society, 2020)
The Gaia-ESO Survey (GES) observed many open clusters as part of its programme to spectroscopically characterize the various Milky Way populations. GES spectroscopy and Gaia astrometry from its second data release are used ...
Homogeneous photometry and star counts in the field of 9 Galactic star clusters
(Elsevier B.V., 2009-05-28)
We present homogeneous V, I CCD photometry of nine stellar fields in the two inner quadrants of the
Galactic plane. The lines-of-view to most of these fields aim in the direction of the very inner Galaxy,
where the ...
Towards a comprehensive knowledge of the open cluster Haffner 9
(Wiley Blackwell Publishing, Inc, 2017-01)
We turn our attention to Haffner 9, aMilkyWay open cluster whose previous fundamental parameter estimates are far from being in agreement. In order to provide with accurate estimates, we present high-quality Washington CT1 ...
PyUPMASK: An improved unsupervised clustering algorithm
(EDP Sciences, 2021-06)
Aims. We present pyUPMASK, an unsupervised clustering method for stellar clusters that builds upon the original UPMASK package. The general approach of this method makes it plausible to be applied to analyses that deal ...
Candidate star clusters toward the inner Milky Way discovered on deep-stacked KS-band images from the VVV Survey
(EDP Sciences, 2017-04)
The census of star clusters in the inner Milky Way is incomplete because of extinction and crowding. Aims. We embarked on a program to expand the star cluster list in the direction of the inner Milky Way using deep stacks ...
Measurement of the epicycle frequency in the Galactic disc and initial velocities of open clusters
(WILEY-BLACKWELL, 2008)
A new method to measure the epicycle frequency kappa in the Galactic disc is presented. We make use of the large data base on open clusters completed by our group to derive the observed velocity vector (amplitude and ...
