Iron abundances from high - resolution spectroscopy of the open clusters NGC 2506 , NGC 6134 , and IC 4651 ⋆
This is the first of a series of papers devoted to derive the metallicity of old open clusters in order to study the time evolution of the chemical abundance gradient in the Galactic disk. We present detailed iron abundances from high resolution (R ∼ > 40, 000) spectra of several red clump and bright giant stars in the open clusters IC 4651, NGC 2506 and NGC 6134. We observed 4 stars of NGC 250...
متن کاملAstronomy and Astrophysics Soft X-ray Emission from Intermediate-age Open Clusters: Ic 4651
We present the results of soft X-ray observations of the intermediate-age open cluster IC 4651 performed with the ROSAT PSPC. We detected 25 sources. Two are identified with a giant binary and a blue straggler respectively, both belonging to the cluster, and two with probable main-sequence members. Two other cases have ambiguous identification. Of the five binaries known in the cluster, the one...
متن کاملThe chromospheric emission of solar - type stars in the young open clusters IC 2391 and IC 2602
In this paper we present chromospheric emission levels of the solar-type stars in the young open clusters IC 2391 and IC 2602. High resolution spectroscopic data were obtained for over 50 F, G, and K stars from these clusters over several observing campaigns using the University College London Echelle Spectrograph on the 3.9-m Anglo-Australian Telescope. Unlike older clusters, the majority (28/...

متن کاملDetailed chemical composition of the open cluster IC 4651 : The iron peak , α elements , and Li . ⋆
Detailed chemical composition of the open cluster IC 4651: The iron peak, α elements, and Li. Abstract. We present a detailed chemical analysis of 22 stars along the colour-magnitude sequence of the intermediate-age (1.7 Gyr) open cluster IC 4651, based on high-resolution, high S/N ratio spectra from UVES/VLT. IC 4651 thus becomes one of the few open clusters for which a detailed composition an...
