Observations of IC 348 : The Disk Population at 2 - 3 Million Years
نویسنده
چکیده
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 to both investigate the frequency and nature of the circumstellar disk population in the cluster. The Spitzer observations span a wavelength range between 3.6 and 24 μm corresponding to disk radii of ∼ 0.1 – 5 AU from the

We report the results of the first sensitive L-band (3.4 μm) imaging survey of the young IC 348 cluster in Perseus. In conjunction with previously acquired JHK (1.25, 1.65, 2.2 μm) observations, we use L-band data to obtain a census of the circumstellar disk population to mK = mL ≤ 12.0 in the central ∼ 110 arcmin 2 region of the cluster. An analysis of the JHKL colors of 107 sources indicates ...

A 5.2×5.2 region toward the young cluster IC 348 has been imaged in the millimeter continuum at 4.0×4.9 resolution with the OVRO interferometer to a RMS noise level of 0.75mJybeam−1 at 98 GHz. The data are used to constrain the circumstellar disk masses in a cluster environment at an age of ∼ 2 Myr. The mosaic encompasses 95 known members of the IC 348 cluster with a stellar mass distribution t...
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...
متن کاملTesting the Disk Regulation Paradigm with Spitzer Observations . I . Rotation Periods of Pre - main Sequence Stars in the IC 348 Cluster
We present 105 stellar rotation periods in the young cluster IC 348, 75 of which are new detections, increasing the total number of known periods in this cluster to 143. The period distribution resembles that seen in the heart of the Orion Nebula Cluster by Herbst and colleagues. Stars estimated to be less massive than 0.25 M ⊙ show a unimodal distribution of fast rotators (P ∼ 1–2 days) and a ...
متن کاملThe Evolutionary State of Anemic Circumstellar Disks in IC 348 and The Primordial-to-Debris Disk Transition
We investigate the evolution of ∼ 3 Myr-old MIPS-detected circumstellar disks in IC 348 that may be in an intermediate stage between primordial, optically-thick disks of gas/dust and debris disks characteristic of the final stages of planet formation. We demonstrate that these anemic disks are not a homogenous class of objects corresponding to a unique evolutionary state. Rather, such disks aro...
