The spatial distribution of stars in open clusters
The analysis of the distribution of stars in open clusters may yield important information on the star formation process and early dynamical evolution of stellar clusters. Here we address this issue by systematically characterizing the internal spatial structure of 16 open clusters in the Milky Way spanning a wide range of ages. Cluster stars have been selected from a membership probability ana...
متن کاملSearch and analysis of blue straggler stars in open clusters
Aims. This paper presents a new homogeneous catalogue of blue straggler stars (BSS) in Galactic open clusters. Methods. Photometric data for 216 clusters were collected from the literature and 2782 BSS candidates were extracted from 76 of them. Results. We found that the anticorrelation of BSS frequency vs. total magnitude identified in similar studies conducted on Galactic globular clusters ex...
متن کاملVariability of Be Stars in Southern Open Clusters
We recently discovered a large number of highly active Be stars in the open cluster NGC 3766, making it an excellent location to study the formation mechanism of Be star disks. To explore whether similar disk appearances and/or disappearances are common among the Be stars in other open clusters, we present here multiple epochs of Hα spectroscopy for 296 stars in eight open clusters. We identify...
متن کاملAsteroseismology of δ Scuti stars in open clusters: Praesepe
The present paper provides a general overview of the asteroseismic potential of δ Scuti stars in clusters, in particular focusing on convection diagnostics. We give a summarise of the last results obtained by the authors for the Praesepe cluster of which five δ Scuti stars are analysed. In that work, linear analysis is confronted with observations, using refined descriptions for the effects of ...
متن کاملA search for delta Scuti stars in northern open clusters
In an effort to test stellar structure and evolution models, analysis of oscillations in A and F stars in open clusters is carried out by the STACC network (Frandsen 1992). In this paper we describe our effort to locate a suitable open cluster in the northern hemisphere for a future multi-site campaign.We present BV Johnson and time series CCDphotometry of four poorly studied open clusters: NGC...
