Trumpler 20 - an old and rich open cluster ⋆ † ‡
We show that the open cluster Trumpler 20, contrary to the earlier findings, is actually an old Galactic open cluster. New CCD photometry and high-resolution spectroscopy are used to derive the main parameters of this cluster. At [Fe/H]=−0.11 for a single red giant star, the metallicity is slightly subsolar. The best fit to the color-magnitude diagrams is achieved using a 1.3 Gyr isochrone with...
متن کاملThe old metal-poor open cluster ESO 92-SC05: accreted from a dwarf galaxy?
The study of old open clusters outside the solar circle can bring constraints on formation scenarios of the outer disk. In particular, accretion of dwarf galaxies has been proposed as a likely mechanism in the area. We use BVI photometry for determining fundamental parameters of the faint open cluster ESO 92-SC05. Colour-Magnitude Diagrams are compared with Padova isochrones, in order to derive...
متن کاملThe old anticentre open cluster Berkeley 32 : membership and fundamental parameters ⋆
We have obtained medium-low resolution spectroscopy and BV I CCD imaging of Berkeley 32, an old open cluster which lies in the anticentre direction. From the radial velocities of 48 stars in the cluster direction we found that 31 of them, in crucial evolutionary phases, are probable cluster members, with an average radial velocity of +106.7 (σ = 8.5) km s. From isochrone fitting to the colour m...
متن کاملBerkeley 22 , an old and distant open cluster towards the Galactic anticentre
We present deep CCD BV I photometry of the distant, old open cluster Berkeley 22, covering from the red giants branch (RGB) to about 6 magnitudes below the main sequence (MS) turn-off. Using the synthetic Colour Magnitude Diagram method with three different types of stellar evolutionary tracks, we estimate values and theoretical uncertainty of distance modulus (m-M)0, reddening E(B−V ) , age τ ...
متن کاملMembership and lithium in the old , metal – poor open cluster Berkeley 32 ⋆
Context. Measurements of lithium (Li) abundances in open clusters provide a unique tool for following the evolution of this element with age, metallicity, and stellar mass. In spite of the plethora of Li data already available, the behavior of Li in solar–type stars has so far been poorly understood. Aims. Using FLAMES/Giraffe on the VLT, we obtained spectra of 157 candidate members of the old,...
