Using both SPIRE at 250/350/500 üm and PACS at 70/160 üm or 100/160 üm, the HOBYS survey provides an unbiased and complete census of intermediate- to high-mass young stellar objects, some of which are not detected by Spitzer. Key core properties, such as bolometric luminosity and mass (as derived from spectral energy distributions), are used to constrain their evolutionary stages. We identify a handful of high-mass prestellar cores and show that their lifetimes could be shorter in the Rosette molecular complex than in nearby low-mass star-forming regions. We also quantify the impact of expanding H ii regions on the star formation process acting in both Rosette and RCW 120. Herschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA.Figures 4 and 5 are only available in electronic form at <A href="http://www.aanda.org">http://www.aanda.org</A> | Free Keywords: | stars: formation; stars: massive; telescopes; stars: protostars; H ii regions; dust; extinction | External Publication Status: | published | Document Type: | Article |
