Description We propose complete surveys of the MonR2 (830 pc) and CepOB3 (700 pc) molecular clouds with SPIRE and PACS on Herschel to complement extant surveys with NEWFIRM and Spitzer at near-IR and mid-IR wavelengths, respectively. These two clouds complement cloud surveys of Orion and the Gould Belt clouds, as they are actively forming both low and high mass stars, and they are found at different evolutionary states relative to Orion. They are also closer to the galactic plane than Orion, implying a higher density of background stars and more reliable extinction maps. This study will impact our knowledge of two essential problems in star formation: the physical factors which determine the star formation rate and the initial mass function. We will produce high resolution maps of the large-scale dust column density and temperature from the SPIRE data maps and compare these to the density of protostars to determine the rate of star formation per area relative to the gas column density. We will use this data to reconcile inconsistent star formation rate vs gas column density correlations recently reported in the literature by measuring this relationship by independent means in a single cloud. To study the IMF, and its possible dependence on environment, we will look at factors that may determine the IMF: the mass of the pre-stellar core and the protostellar luminosity (which has a significant contribution from accretion). Pre-stellar cores will be extracted and characterized in terms of structure and mass. By combining the protostellar SEDs from Spitzer with PACS photometry, particularly 70~ mu m, better characterization of protostar bolometric luminosity and temperature distributions can be produced and compared among the clouds observed. With this data, we can examine how the core mass function and protostellar luminosity function can vary with density of young stars and cores and with the local conditions of the mol...

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 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
