The old open clusters Saurer A, B and C revisited
(Wiley Blackwell Publishing, Inc, 2003-11)
We report deep (V ≈ 24.0) VI CCD photometry of three fields centred in the regions of the old open clusters Saurer A, B and C. In the case of Saurer A, which is considered one of the oldest known open clusters, we also ...
Diagnostic tool to analyse colour-magnitude diagrams of poorly populated stellar concentrations
(WILEY-BLACKWELL, 2011)
The dynamical processes that lead to open cluster disruption cause its mass to decrease. To investigate such processes from the observational point of view, it is important to identify open cluster remnants (OCRs), which ...
First CCD UBVI photometric analysis of four moderately young open clusters in the third galactic quadrant
(Wiley Blackwell Publishing, Inc, 2010-10)
We present CCD photometry in the Johnson UBV and Kron-Cousins I systems down to V~ 22.0 for the open clusters NGC 2311, Trumpler 6, NGC 2432 and BH 54 and their surrounding fields. Trumpler 6 and BH 54 have never been ...
New fundamental parameters of the Galactic open clusters Berkeley 26, Czernik 27, Melotte 72, NGC 2479 and BH 37
(Wiley Blackwell Publishing, Inc, 2010-03)
We have obtained CCD UBVIKC photometry down to V∼ 21.0 for the open clusters Berkeley 26, Czernik 27, Melotte 72, NGC 2479 and BH 37. The latter has never been studied before. Cluster stellar density profiles were obtained ...
Open clusters: III. Fundamental parameters of B stars in NGC 6087, NGC 6250, NGC 6383 and NGC 6530. B type stars with circumstellar envelopes.
(EDP Sciences, 2018-02)
Context. Stellar physical properties of star clusters are poorly known and the cluster parameters are often quite uncertain.Aims. Our goals are to perform a spectrophotometric study of the B star population in open clusters ...
