Dense Cores in Perseus: the Influence of Stellar Content and Cluster Environment
We present the chemistry, temperature, and dynamical state of a sample of 193 dense cores or core candidates in the Perseus Molecular cloud and compare the properties of cores associated with young stars and clusters with those which are not. The combination of our NH3 and CCS observations with previous millimeter, sub-millimeter, and Spitzer data available for this cloud enable us both to dete...
متن کاملThe Dynamics of Dense Cores in the Perseus Molecular Cloud II: the Relationship between Dense Cores and the Cloud
We utilize the extensive datasets available for the Perseus molecular cloud to analyze the relationship between the kinematics of small-scale dense cores and the larger structures in which they are embedded. The kinematic measures presented here can be used in conjunction with those discussed in our previous work as strong observational constraints that numerical simulations (or analytic models...
متن کاملcontent analysis of l1 and l2 writing textbooks and the perception analysis of university professors on the influence of english writing expertise on the persian in an efl context
the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...

15 صفحه اولThe structure and dynamics of the dense cores in the Perseus molecular cloud complex
We have produced wide-field (>∼0.1 deg2) images of the molecular gas around the dense cores observed by Ladd et al. (1994) in the Perseus cloud complex in various CO (CO(1–0), 13CO(1–0), C18O(1–0)) and CS (CS(2–1), C34S(2–1)) isotopomers, and N2H(1–0), using the 16-element focal plane array operating at a wavelength of 3 mm at the Five College Radio Astronomy Observatory. We also performed mosa...
