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 کاملExpansion Parallax of the Planetary Nebula Ic 418
In this paper, we present radio continuum observations of the planetary nebula IC 418 obtained at two epochs separated by more than 20 years. These data allow us to show that the angular expansion rate of the ionization front in IC 418 is 5.8 ± 1.5 mas yr−1. If the expansion velocity of the ionization front is equal to the expansion velocity of the gas along the line of sight as measured by opt...
متن کاملDeep MIPS Observations of the IC 348 Nebula: Constraints on the Evolutionary State of Anemic Circumstellar Disks and the Primordial-to-Debris Disk Transition
We describe new, deep MIPS photometry and new high signal-to-noise optical spectroscopy of the 2.5 Myr-old IC 348 Nebula. To probe the properties of the IC 348 disk population, we combine these data with previous optical/infrared photometry and spectroscopy to identify stars with gas accretion, to examine their mid-IR colors, and to model their spectral energy distributions. IC 348 contains man...
