چکیده
We imaged a 2 × 2 region of the Orion Nebula cluster in 1.3 mm wavelength continuum emission with the recently commissioned Combined Array for Research in Millimeter Astronomy (CARMA) and with the Submillimeter Array Miller Institute for Basic Research in Science, Berkeley, CA 94720 Steward Observatory, University of Arizona, Tucson, AZ 85721

The (sub-)millimeter SED of protoplanetary disks in the outskirts of the Orion nebula cluster
We present the sub-mm/mm SED for a sample of eight young circumstellar disks in the outer regions of the Orion nebula cluster (ONC). New observations were carried out at 2.9 mm with the CARMA array and for one disk, 216-0939, at 3.3 and 6.8 mm with ATCA. By combining these new millimeter data with literature measurements at sub-millimeter wavelengths we investigate grain growth and measure the ...
متن کاملThe Masses of the Orion Proplyds from Submillimeter Dust Emission
We have imaged the 880 μm continuum emission from the “proplyds” in the center of the Trapezium Cluster in Orion using the Submillimeter Array with a beam size 1. 5 FWHM and an rms of 2.7 mJy. Five sources are detected with fluxes in the range 18 to 38 mJy, which includes dust emission from four proplyds and ionized gas from θ OriG. The total masses of the detected proplyds derived from their d...
متن کاملX-ray Emission from Orion Nebula Cluster Stars with Circumstellar Disks and Jets
We investigate the X-ray and near-infrared emission properties of a sample of pre-main sequence (PMS) stellar systems in the Orion Nebula Cluster (ONC) that display evidence for circumstellar disks (“proplyds”) and optical jets in Hubble Space Telescope (HST) imaging. Our study uses X-ray data acquired during Chandra Orion Ultradeep Program (COUP) observations, as well as complementary optical ...
متن کاملSubmillimeter studies of circumstellar disks in Taurus and Orion
We highlight two recent studies of circumstellar disks in the Taurus and Orion star forming regions. Using the JCMT and CSO, we measure disk fluxes in Taurus over a wide range of submillimeter wavelengths and determine the frequency dependence of the dust opacity. We find clear evidence for a systematic change in its behavior with time, most readily explained by grain growth. Using the SMA, we ...
