Galactic CHaMP. II. Dense gas clumps.
Listed in IVOA Registry (Virtual Observatory)
The Census of High- and Medium-mass Protostars (CHaMP) is the first large-scale (280{deg}<l<300{deg}, -4{deg}<b<2{deg}), unbiased, subparsec resolution survey of Galactic molecular clumps and their embedded stars.
Description
Barnes et al. (Paper I, 2011, J/ApJS/196/12) presented the source catalog of ~300 clumps based on HCO^+^(1-0) emission, used to estimate masses M. Here we use archival midinfrared-to-millimeter continuum data to construct spectral energy distributions.
Fitting two-temperature gray-body models, we derive bolometric luminosities, L. We find that the clumps have 10<~L/L_{sun}_<~10^6.5^ and 0.1<~L/M/[L_{sun}_/M_{sun}_]<~10^3^, consistent with a clump population spanning a range of instantaneous star-formation efficiencies from 0 to ~50%. We thus expect L/M to be a useful, strongly varying indicator of clump evolution during the star cluster formation process.
