Radial velocities of Berkeley 32 stars
Listed in IVOA Registry (Virtual Observatory)
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.
Description
In spite of the plethora of Li data already available, the behavior of Li in solar-type stars has so far been poorly understood. Using FLAMES/Giraffe on the VLT, we obtained spectra of 157 candidate members of the old, metal-poor cluster Berkeley 32, to determine membership and to study the Li behavior of confirmed members.
Radial velocities were measured, allowing us to derive both the cluster velocity and membership information for the sample stars. The Li abundances were obtained from the equivalent width of the Li I 670.8nm feature, using curves of growth.
