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
70virgul 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 w...ith density of young stars and cores
and with the local conditions of the molecular gas, and how these vary from
cloud 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.
