Membership , lithium , and metallicity in the young open clusters IC 2602 and IC 2391 : enlarging the sample ⋆ ⋆ ⋆
We present lithium abundances for ∼50 X-ray selected candidate members of the 30–50 Myr old open clusters IC 2602 and IC 2391. These data enlarge and extend to cooler temperatures previous Li surveys of these clusters by Stauffer et al. (1989) and Randich et al. (1997). We also give for the first time an estimate of the metallicity of the two clusters which turns out to be close to solar. Radia...
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 کاملHubble Space Telescope Survey of the Perseus Cluster: II. Photometric scaling relations in different environments
We investigate the global photometric scaling relations traced by early-type galaxies in different environments, ranging from dwarf spheroidals, over dwarf elliptical galaxies, up to giant ellipticals (−8mag & MV & −24 mag). These results are based in part on our new HST/ACS F555W and F814W imagery of dwarf spheroidal galaxies in the Perseus Cluster. The full sample, built from our HST images a...
متن کاملPhotometric variability in the old open cluster M 67 ⋆ II .
We use differential CCD photometry to search for variability in BV I among 990 stars projected in and around the old open cluster M67. In a previous paper we reported results for 22 cluster members that are optical counterparts to X-ray sources; this study focuses on the other stars in our observations. A variety of sampling rates were employed, allowing variability on time scales ranging from ...
متن کاملThe low mas end of the young cluster IC 2391
By collecting optical and infrared photometry, as well as medium resolution spectroscopy, we have discovered a sample of low mass stars and brwon dwarfs in the young cluster IC2391. Using the lithium depletion boundary near the substellar limit, we have estimated the age of the cluster as ∼50 Myr. We have also estudied the Hα emission in this sample.
