cds-question@unistra.frradio-continuum-emissionradio-sourcesyoung-stellar-objectsastronomical-object-identificationWe present Karl G. Jansky Very Large Array 1.3, 3.6, and 6cm continuum maps of compact radio sources in the Orion Nebular Cluster (ONC). We mosaicked 34arcmin^2^ at 1.3cm, 70arcmin^2^ at 3.6cm and 109arcmin^2^ at 6cm, containing 778 near-infrared detected young stellar objects and 190 Hubble Space Telescope-identified proplyds (with significant overlap between those characterizations). We detected radio emission from 175 compact radio sources in the ONC, including 26 sources that were detected for the first time at these wavelengths. For each detected source, we fitted a simple free-free and dust emission model to characterize the radio emission. We extrapolate the free-free emission spectrum model for each source to ALMA bands to illustrate how these measurements could be used to correctly measure protoplanetary disk dust masses from submillimeter flux measurements. Finally, we compare the fluxes measured in this survey with previously measured fluxes for our targets, as well as four separate epochs of 1.3cm data, to search for and quantify the variability of our sources.2016ApJ...831..155Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/831/155CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/790/49 : Gould's Belt VLA survey.
