Star Formation in IC 348
A review of work on the small, compact, nearby young cluster IC 348 is given. This region is particularly important because it is well surveyed at a variety of wavelengths and intermediate in nature between dense clusters and loose associations. Its earliest type star is B5 and it contains a few hundred stellar members as well as some brown dwarfs, protostars, Herbig-Haro objects and starless s...
متن کاملDeep UBVRI photometry in IC 348 ? ? ?
Deep UBVRI-CCD Johnson photometry for 123 stars in the densest region of IC348 open cluster were obtained during three observational runscolour and colour-magnitude diagrams allowed us to classify 114 stars as members of the cluster and to connrm a large presence of pre-main sequence stars. Individual reddening values were computed for the brightest members. The structure and sub-clustering wer...
متن کاملStar formation in the vicinity of the IC 348 cluster
Aims. We present molecular line observations of the southwestern part of the IC 348 young cluster, and we use them together with NIR and mm continuum data to determine the distribution of dense gas, search for molecular outflows, and analyze the ongoing star formation activity in the region. Methods. Our molecular line data consists of C 18 O(1–0) and N 2 H + (1–0) maps obtained with the FCRAO ...
متن کاملObservations of IC 348 : The Disk Population at 2 - 3 Million Years
We present near and mid-infrared photometry obtained with the Spitzer Space Telescope of ∼ 300 known members of the IC 348 cluster. We merge this photometry with existing ground-based optical and near-infrared photometry in order to construct optical-infrared spectral energy distributions (SEDs) for all the cluster members and present a complete atlas of these SEDs. We employ these observations...
متن کاملLow-mass binaries in the young cluster IC 348: implications for binary formation and evolution
We report on a near-infrared adaptive optics survey of a sample of 66 low-mass members of the premain sequence stellar cluster IC 348. We find 12 binary systems in the separation range 0. 1–8, excluding 3 probable background projected companions. An estimate of the number of faint undetected companions is derived, before we evaluate the binary frequency in this cluster. In the range logP =5.0–7...
