Description One of the closest massive star-forming regions known, and surprisingly
one of the least studied, is the Onsala 2 (ON2) complex in Cygnus at
d = 1.2 kpc. The ON2 region shows numerous signs of active high-mass
star-formation including OH masers, compact and ultracompact HII regions,
and luminous molecular outflows. A unique feature of ON2 is that it
harbors the rare and remarkable Wolf-Rayet star WR 142, a strong
UV source whose hypersonic wind is driving shock waves throughout
the region. We propose to conduct the first comprehensive IR
study of ON2 using PACS and SPIRE, supplemented by existing
Spitzer IRAC/MIPS data and high resolution Chandra X-ray data.
This study will build on (and complement) our X-ray study of ON2
already in progress. Our primary goal is to develop a broad picture
of how star-formation is proceeding in ON2 and to identify environmental
factors that may be affecting it (e.g. ionization and shocks associated
with HII regions and WR 142). We will identify and classify all IR-excess
YSOs, including the population of embedded sources and low-mass YSOs about
which little is yet known. We will determine if filamentary structures
containing YSOs are present and will use information on the spatial
distribution of YSOs relative to strong ionizing sources to search
for evidence of triggered star formation. Aperture photometry will
provide information on the physical properties of individual YSOs
and a dust temperature map of ON2. Steep temperature gradients are
expected near strong ionizing HII regions, one of which is known
to be a source of hard diffuse X-rays. We also propose to obtain
targeted SPIRE FTS spectroscopy of the massive YSO IRAS 20198+3716
to determine properties of the gas in its vicinity.

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.
