Low-mass members of the young cluster IC 4665 and pre-main-sequence lithium depletion

We have used fibre spectroscopy to establish cluster membership and examine premain-sequence (PMS) lithium depletion for low-mass stars (spectral types F to M) in the sparse young (≃ 30Myr) cluster IC 4665. We present a filtered candidate list of 40 stars that should contain 75 per cent of single cluster members with 11.5 < V < 18 in the central square degree of the cluster. Whilst Fand G-type ...

Detection of the lithium depletion boundary in the young open cluster IC 4665 ⋆

Context. The so-called lithium depletion boundary (LDB) provides a secure and independent tool for deriving the ages of young open clusters. Aims. In this context, our goal is to determine membership for a sample of 147 photometrically selected candidates of the young open cluster IC 4665 and to use confirmed members to establish an age based on the LDB. Methods. Employing the FLAMES multi-obje...
