J/ApJ/663/1149    Spitzer survey of Serpens YSO population    (Harvey+, 2007)

The Spitzer c2d survey of large, nearby, interstellar clouds. IX. The Serpens YSO population as observed with IRAC and MIPS. Harvey P., Merin B., Huard T.L., Rebull L.M., Chapman N., Evans II N.J., Myers P.C. <Astrophys. J., 663, 1149-1173 (2007)> =2007ApJ...663.1149H
ADC_Keywords: Surveys ; Infrared sources Mission_Name: Spitzer Keywords: infrared: general Abstract: We discuss the combined IRAC/MIPS c2d Spitzer Legacy observations of the Serpens star-forming region. We describe criteria for isolating bona fide YSOs from the extensive background of extragalactic objects. We then discuss the properties of the resulting high-confidence set of 235 YSOs. An additional 51 lower confidence YSOs outside this area are identified from the MIPS data and 2MASS photometry. We present color-color diagrams to compare our observed source properties with those of theoretical models for star/disk/envelope systems and our own modeling of the objects that are well represented by a stellar photosphere plus circumstellar disk. Description: The parameters of our observations have already been described in detail in Paper II (Harvey et al., 2006ApJ...644..307H) for IRAC and in a companion study (Harvey et al., 2007ApJ...663.1139H) for MIPS.

Note (1): SED type defined as follows: T = SED identical to a Classical T Tauri star, within the errors L = SED with lower fluxes at some wavelengths than a Classical T Tau star H = SED with larger fluxes at some wavelengths than a Classical T Tau star LU = photospheric fluxes up to around 8 micron but then a sudden jump at longer wavelengths to the levels of a T-Tauri disk. Note (2): Starting at the last wavelength where the observed flux is photospheric (λexcess).
