High-resolution CARMA Observation of Molecular Gas in the North America and Pelican Nebulae

In this paper, we present the first results from a CARMA high-resolution 12CO(1-0), 13CO(1-0), and C18O(1-0) molecular line survey of North America Pelican (NAP) Nebulae. observations have been combined with single-dish data Purple Mountain 13.7 m telescope, to add short spacings produce high-dynamic-range images. We find that gas is predominantly shaped by W80 H ii bubble, driven an O star. Several bright rims noted in observation are probably remnant clouds, heated stripped massive Matching these lines optical images, construct model three-dimensional structure NAP complex. Two groups clumps/filaments on near side bubble: one being pushed toward us, whereas other moving bubble. Another group far away. The young stellar objects Gulf region reside three different clusters, each hosted cloud clump groups. Although all content impacted feedback central star, some regions show no signs star formation, while areas clearly exhibit formation activity. Additional carved includes cometary structures Head region, boomerang features at boundary region. complex ideal place for study effects formation.
