cds-question@unistra.frinterstellar-mediuminfrared-photometryradio-astronomygalaxy-kinematicsmolecular-cloudsmilky-way-galaxyWe present the first Herschel PACS and SPIRE photometric observations in a portion of the outer Galaxy (216.5{deg}<~l<~225.5{deg} and -2{deg}<~b<~0{deg}) as a part of the Hi-GAL survey. The maps between 70 and 500{mu}m, the derived column density and temperature maps, and the compact source catalog are presented. NANTEN CO(1-0) line observations are used to derive cloud kinematics and distances so that we can estimate distance-dependent physical parameters of the compact sources (cores and clumps) having a reliable spectral energy distribution that we separate into 255 proto-stellar and 688 starless sources. Both typologies are found in association with all the distance components observed in the field, up to ~5.8kpc, testifying to the presence of star formation beyond the Perseus arm at these longitudes. Selecting the starless gravitationally bound sources, we identify 590 pre-stellar candidates. Several sources of both proto- and pre-stellar nature are found to exceed the minimum requirement for being compatible with massive star formation based on the mass-radius relation. For the pre-stellar sources belonging to the Local arm (d<~1.5kpc) we study the mass function whose high-mass end shows a power law N(logM){propto}M^-1.0+/-0.2^. Finally, we use a luminosity versus mass diagram to infer the evolutionary status of the sources, finding that most of the proto-stellar sources are in the early accretion phase (with some cases compatible with a Class I stage), while for pre-stellar sources, in general, accretion has not yet started.2013ApJ...772...45Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/772/45CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVI/139 : Herschel Observation Log (Herschel Science Centre, 2013)VII/50 : CO Radial Velocities Toward Galactic H II Regions (Blitz+ 1982)VII/7 : Lynds' Catalogue of Dark Nebulae (LDN) (Lynds 1962)VII/20 : Catalogue of HII Regions (Sharpless 1959)J/A+A/549/A130 : YSOs in Herschel-Hi-GAL survey (Veneziani+, 2013)J/A+A/537/A1 : Infrared fluxes of HII regions and PNe (Anderson+, 2012)J/A+A/526/A151 : Hi-Gal sources distance determination (Russeil+, 2011)J/AJ/137/4072 : Infrared photometry of G216-2.5 YSOs (Megeath+, 2009)J/ApJ/686/948 : CO in extragalactic giant molecular clouds (Bolatto+, 2008)J/ApJ/684/1240 : Prestellar cores in Perseus, Serpens & Oph.
