Description Massive stars are rare and distant. Their short-lived protostellar phases are therefore difficult to
study, and the processes that produce them are not well understood. The Cygnus-X complex is one
of the richest known regions of star formation in the Galaxy at a distance of virgul1.3 kpc, which allows
it to be studied at smaller scales and less confusion than other similarly active regions that are more
distant. We have conducted a Spitzer Legacy survey of the Cygnus-X region and used the data to
map the distribution of Class I and II YSOs in the complex, and have begun to study the interaction
between the massive young stars and clusters of low-mass YSOs.
We propose to use PACS and SPIRE to complete an unbiased survey in the Cygnus-X region to
detect the intermediate to high-mass young stellar objects, pre-stellar cores, and infrared dark clouds
(IRDCs) and their embedded objects. The Herschel observations, in conjunction with
the existing Spitzer, near-IR, and other ancillary datasets will allow us to assemble a
comprehensive picture of star formation in this high mass, extremely active complex. With the
Herschel data we will 1) complete the sample of massive protostars and YSOs in Cygnus-X and
construct SEDs of the objects from 1 to 1200 microns, 2) use the derived luminosities and
envelope masses from the sample to construct evolutionary diagrams and test high-mass star
formation models, 3) analyze the population of Infrared Dark Clouds in Cygnus-X, and 4) explore
the role of massive stars in triggering star formation in surrounding clouds. The data will provide a
useful resource for the study of star formation for years to come.

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.
