On the Galactic Disk Metallicity Distribution from Open Clusters I. New Catalogues and Abundance Gradient
In this paper we have compiled two new open cluster catalogues. In the first one, there are 119 objects with ages, distances and metallicities available, while in the second one, 144 objects have both absolute proper motion and radial velocity data, of which 45 clusters also with metallicity data available. Taking advantages of the large number of objects included in our sample, we present an i...
متن کاملBlue Straggler Stars in Galactic Open Clusters and the effect of field star contamination
Context. We investigate the distribution of Blue Straggler stars in the field of three open star clusters. Aims. The main purpose is to highlight the crucial role played by general Galactic disk fore-/background field stars, which are often located in the same region of the Color Magnitude Diagram as Blue Straggler stars. Methods. We analyze photometry taken from the literature of 3 open cluste...
متن کاملFast rotating massive stars and the origin of the abundance patterns in galactic globular clusters
Aims. We propose the Wind of Fast Rotating Massive Stars scenario to explain the origin of the abundance anomalies observed in globular clusters. Methods. We compute and present models of fast rotating stars with initial masses between 20 and 120 M⊙ for an initial metallicity Z=0.0005 ([Fe/H] ≃ −1.5). We discuss the nucleosynthesis in the H-burning core of these objects and present the chemical...
متن کاملGalactic Open Clusters
The study of open clusters has a classic feel to it since the subject predates anyone alive today. Despite the age of this topic, I show via an ADS search that its relevance and importance in astronomy has grown faster in the last few decades than astronomy in general. This is surely due to both technical reasons and the interconnection of the field of stellar evolution to many branches of astr...
متن کاملStar cluster stability and the effects of binary stars: Galactic open clusters
The diagnostic age versus mass-to-light ratio diagram is often used in attempts to constrain the shape of the stellar initial mass function (IMF), and the stability and the potential longevity of extragalactic young to intermediate-age massive star clusters. Here, we explore its potential for Galactic open clusters. On the basis of a homogenised cluster sample we provide useful constraints on t...
