The Diverse Stellar Populations of the W3 Star Forming Complex
An ∼800 arcmin mosaic image of the W3 star forming complex obtained with the Chandra X-ray Observatory gives a valuable new view of the spatial structure of its young stellar populations. The Chandra image reveals ∼ 1300 faint X-ray sources, most of which are PMS stars in the cloud. Some, but not all, of the high-mass stars producing hypercompact and ultracompact HII (UCHII) regions are also se...
متن کاملStar Formation in the Orion-monoceros Complex
Pre-main sequence stars in the Orion-Monoceros Complex are either distributed in groups closed associated with dense cores, or dispersed along molecular filaments. Some molecular clouds are apparently affected by the OrionEridanus Superbubble created by the Wolf-Rayet winds and supernovae from the OriOB1 association, whose shock fronts compressed and triggered starbirth in adjacent molecular cl...
متن کاملStar Formation in the Rosette Complex
The Rosette Complex in the constellation of Monoceros is a magnificent laboratory for the study of star formation. The region presents an interesting scenario, in which an expanding HII region generated by the large OB association NGC 2244 is interacting with a giant molecular cloud. Inside the cloud a number of stellar clusters have formed recently. In this chapter we present a review of past ...
متن کاملThe star-forming content of the W3 giant molecular cloud
We have surveyed a ∼0.9-square-degree area of the W3 giant molecular cloud and star-forming region in the 850-μm continuum, using the SCUBA bolometer array on the James Clerk Maxwell Telescope. A complete sample of 316 dense clumps was detected with a mass range from around 13 to 2500M⊙. Part of the W3 GMC is subject to an interaction with the Hii region and fast stellar winds generated by the ...
متن کاملStar Formation across the Taffy Bridge: Ugc 12914/15
We present BIMA two-field mosaic CO(1-0) images of the Taffy galaxies (UGC 12914/15), which show the distinct taffy-like radio continuum emission bridging the two spiral disks. Large amounts of molecular gas (1.4 × 10M⊙, using the standard Galactic CO-to-H2 conversion applicable to Galactic disk giant molecular clouds [GMCs]) were clearly detected throughout the taffy bridge between the two gal...
