J/AJ/130/1763       11.7µm point sources in Orion              (Smith+, 2005)

Thermal dust emission from proplyds, unresolved disks, and shocks in the Orion nebula. Smith N., Bally J., Shuping R.Y., Morris M., Kassis M. <Astron. J., 130, 1763-1777 (2005)> =2005AJ....130.1763S

The map covers 2.7'x1.6', with a diffraction-limited spatial resolution of 0.35"; it includes the BN/KL region, the Trapezium, and OMC-1 South. Excluding BN/KL, we detect 91 thermal-IR point sources, with 27 known proplyds and over 30 "naked" stars showing no extended structure in Hubble Space Telescope (HST) images. Description: Images of the Orion Nebula at 11.7µm (11.09-12.22µm) were obtained on 2004 January 25 using T-ReCS on Gemini South. File Summary:

Note (1): The sources with an "O" are optically visible stars with no extended proplyd structure in HST images (O'Dell & Wong 1996, Cat. J/AJ/111/846) that nevertheless show detectable 11.7µm thermal-IR emission from unresolved dusty disks. "X" denotes an IR point source with no star or proplyd in the list of O'Dell & Wong (1996, Cat. J/AJ/111/846), and the stars θ1(A-E) (* tet01 Ori A in Simbad), members of OMC-1 South, and known proplyds are identified by name. Note (2): Uncertain identifications due to poor agreement in the coordinates.
Nomenclature Notes: Sources are [SBS2005] in Simbad. History: From electronic version of the journal
