AbstractIn this study, "A Herschel study of point sources in infrared dark clouds (IRDCs) in two fields of the Hi-GAL survey", we present a study of point sources on or nearby infrared dark clouds. Using data obtained from the science demonstration phase (SDP) of the Herschel Infrared Galactic Plane Survey (Hi-GAL) at wavelength of 70, 160, 250, 350 and 500 micro metre. The spectral energy distributions of the sources are constructed and modelled by single-component modified blackbody models, and the physical properties of the sources estimated. The point sources are associated with protostars and prestellar cores. Eight of them have masses over 50 Msun, making them excellent candidates to become massive stars. These results support the idea that IRDCs have the capability of forming massive stars or represent the earliest stage of high-mass star formation.
