| Description | We propose complete surveys of the MonR2 (830 pc) and CepOB3 (700 pc) molecularclouds with SPIRE and PACS on Herschel to complement extant surveys withNEWFIRM and Spitzer at near-IR and mid-IR wavelengths, respectively. These twoclouds complement cloud surveys of Orion and the Gould Belt clouds, as they areactively forming both low and high mass stars, and they are found at differentevolutionary states relative to Orion. They are also closer to the galacticplane than Orion, implying a higher density of background stars and morereliable extinction maps. This study will impact our knowledge of twoessential problems in star formation: the physical factors which determine thestar formation rate and the initial mass function. We will produce highresolution maps of the large-scale dust column density and temperature from theSPIRE data maps and compare these to the density of protostars to determine therate of star formation per area relative to the gas column density. We willuse this data to reconcile inconsistent star formation rate vs gas columndensity correlations recently reported in the literature by measuring thisrelationship by independent means in a single cloud. To study the IMF, and itspossible dependence on environment, we will look at factors that may determinethe IMF: the mass of the pre-stellar core and the protostellar luminosity(which has a significant contribution from accretion). Pre-stellar cores willbe extracted and characterized in terms of structure and mass. By combiningthe protostellar SEDs from Spitzer with PACS photometry, particularly70virgul mu m, better characterization of protostar bolometric luminosity andtemperature distributions can be produced and compared among the cloudsobserved. With this data, we can examine how the core mass function andprotostellar luminosity function can vary with density of young stars and coresand with the local conditions of the molecular gas, and how these vary fromcloud to cloud. |

| Mission Description | Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
