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 ...
متن کاملDetection 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...
متن کاملClusters IC 4665 and Cr 359 and a Probable Birthplace of the Pulsar PSR B 1929 + 10
–Based on the epicyclic approximation, we have simulated the motion of the young open star clusters IC 4665 and Collinder 359. The separation between the cluster centers is shown to have been minimal 7 Myr ago, 36 pc. We have established a close evolutionary connection between IC 4665 and the Scorpius-Centaurus association — the separation between the centers of these structures was ≈ 200 pc 15...
متن کاملDance Dance Convolution
Dance Dance Revolution (DDR) is a popular rhythmbased video game. Players perform steps on a dance platform in synchronization with music as directed by on-screen step charts. While many step charts are available in standardized packs, users may grow tired of existing charts, or wish to dance to a song for which no chart exists. We introduce the task of learning to choreograph. Given a raw audi...
متن کامل(IC)LM-FUZZY TOPOLOGICAL SPACES
The aim of the present paper is to define and study (IC)$LM$-fuzzytopological spaces, a generalization of (weakly) induced $LM$-fuzzytopological spaces. We discuss the basic properties of(IC)$LM$-fuzzy topological spaces, and introduce the notions ofinterior (IC)-fication and exterior (IC)-fication of $LM$-fuzzytopologies and prove that {bf ICLM-FTop} (the category of(IC)$LM$-fuzzy topological ...
