J/A+A/468/1009      Star formation in Perseus. II.           (Hatchell+, 2007)

Star formation in Perseus. II. SEDs, classification, and lifetimes. Hatchell J., Fuller G.A., Richer J.S., Harries T.J., Ladd E.F. <Astron. Astrophys., 468, 1009-1024 (2007)> =2007A&A...468.1009H

(2005, Cat. J/A+A/440/151, Paper I) published a submillimetre continuum map of the Perseus molecular cloud, detecting the starless and protostellar cores within it. The aim is to determine the evolutionary stage of each submm core in Perseus, and investigate the lifetimes of these phases. Description: We compile spectral energy distributions (SEDs) from 2MASS (1-2um), Spitzer IRAC (3.6, 4.5, 5.8, 8.0um), Michelle (11 and 18um), IRAS (12, 25, 60, 100um), SCUBA (450 and 850um) and Bolocam (1100um) data. Sources are classified starless/protostellar on the basis of infrared and/or outflow detections and Class I/Class 0 on the basis of Tbol, Lbol/Lsmm and F3.6/F850. In order to investigate the dependence of these evolutionary indicators on mass, we construct radiative transfer models of Class 0 sources. File Summary:

Note (1): Effective radius is sqrt{A/π} where A is the clump area. Note (2): Sources are classed as starless (S) if there is no infrared source or outflow, otherwise the classification is based on the three evolutionary indicators discussed in Sect. 3, which, giving the condition for a Class I are: Tbol>70K, Lbol/Lsmm>3000 and F3.6/F850>0.003. The final classification is based on the majority of the indicators with results of individual indicators given in brackets in the order listed here.
