This book was released on 2012 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This work is about simulations of interstellar chemistry using the deterministic rate equation (RE) method and the stochastic moment equation (ME) method. Primordial metal-poor interstellar medium (ISM) is of our interest and the socalled "Population-II" stars could have been formed in this environment during the "Epoch of Reionization" in the baby universe. We build a gas phase model using the RE scheme to describe the ionization-powered interstellar chemistry. We demonstrate that OH replaces CO as the most abundant metal-bearing molecule in such interstellar clouds of the early universe. Grain surface reactions play an important role in the studies of astrochemistry. But the lack of an accurate yet effective simulation method still presents a challenge, especially for large, practical gas-grain system. We develop a hybrid scheme of moment equations and rate equations (HMR) for large gas-grain network to model astrochemical reactions in the interstellar clouds. Specifically, we have used a large chemical gas-grain model, with stochastic moment equations to treat the surface chemistry and deterministic rate equations to treat the gas phase chemistry, to simulate astrochemical systems as of the ISM in the Milky Way, the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC). We compare the results to those of pure rate equations and modified rate equations and present a discussion about how moment equations improve our theoretical modeling and how the abundances of the assorted species are changed by varied metallicity. We also model the observed composition of H2O, CO and CO2 ices toward Young Stellar Objects in the LMC and show that the HMR method gives a better match to the observation than the pure RE method.

Download or read book Recent Studies in Atomic and Molecular Processes written by Arthur E. Kingston and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sir David Bates celebrated his seventieth birthday on the 18th November 1986. To mark this event a conference was held in the David Bates building at The Queen's University of Belfast on the 17th and 18th November 1986. At this conference ex-students and colleagues of Sir David, who are acknowledged world experts in their field of research, gave in depth reviews of a particular area of atomic and molecular physics. This book on the conference presents a unique account of recent studies in atomic and molecular processes in a wide range of research fields. This volume is dedicated to Sir David by his friends as a token of their affection and respect. It is hoped that it will provide a useful summary of current research in atomic and molecular physics and that it will also show the great contribution which Sir David made to atomic and molecular physics. This conference was supported by the USAF European Office of Aerospace Research and Development who we wish to thank for their generous support. Arthur E.

Book Synopsis Structure/Reactivity and Thermochemistry of Ions by : Pierre Ausloos
Download or read book Structure/Reactivity and Thermochemistry of Ions written by Pierre Ausloos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the proceedings of a 1986 Advanced Study Institute entitled "Structure/Reactivity and Thermochemistry of Ions", held at Les Arcs, France, June 30 to July 11, 1986. The format of a NATO Institute is ideally suited to in-depth communications between scien tists of diverse backgrounds. Particularly in the field of ion physics and chemistry, where on-going research involves physicists, physical chemists, and organic chemists - who use a variety of experimental and theoretical techniques - it is found that in the relaxed but stimula ting atmosphere of a NATO ASI, each professional group provides unique insights, leading to a better definition and solution of problems relating to the properties of gas phase ions. This book presents chapters based on the lectures presented at the Les Arcs ASI. The participants took the initiative to organize a number of specialized workshops - informal discussion groups which considered questions or problem areas of particular interest. The accounts of these sessions, which are also included in this book, make stimulating reading, and include considerable useful information. This Advanced Study Institute is the fourth in a series of NATO-spon sored institutes devoted to the chemistry and physics of ions in the gas phase. The first, in 1974, in Biarritz, France, focussed on "Interactions between Ions and Molecules".

Available in PDF, EPUB and Kindle. Book excerpt: The idea for an international symposium on the interstellar medium was first discussed at the University of Wyoming during the summer of 1984. It was obvious that the outstanding natural beauty of the Teton mountain range in northwestern Wyoming must be matched by a meeting with the broadest appeal to the astronomical community. If the meeting was to produce a book, it must likewise be an important contribution to the astronomical literature. It was for these reasons that early in the discussions, it was decided that the University should host a "school". with the invited speakers presenting tutorials on a broad range of topics involving the interstellar medium. The symposium proceedings would then be a compilation of the written versions of these presentations. It has been nearly a decade since Lyman Spitzer published his classic text on the interstellar medium and we felt the need for a school and book that would focus on the recent developments in our understanding of the inter stellar medium. Thus, we view this two-volume set as an adjunct text to Spitzer's book.

This book was released on 2019-01-03 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This final report represents the completion of the three tasks under the purchase order no. SCPDE5620,1,2F. Chemical composition of gravitationally contracting, but otherwise quiescent, interstellar clouds and of interstellar clouds traversed by high velocity shocks, were modeled in a comprehensive manner that represents a significant progress in modeling these objects. The evolutionary chemical modeling, done under this NASA contract, represents a notable advance over the 'classical' fixed condition equilibrium models because the evolutionary models consider not only the chemical processes but also the dynamical processes by which the dark interstellar clouds may have assumed their present state. The shock calculations, being reported here, are important because they extend the limited chemical composition derivable from dynamical calculations for the total density and temperature structures behind the shock front. In order to be tractable, the dynamical calculations must severely simplify the chemistry. The present shock calculations take the shock profiles from the dynamical calculations and derive chemical composition in a comprehensive manner. The results of the present modeling study are still to be analyzed with reference to astronomical observational data and other contemporary model predictions. As far as humanly possible, this analysis will be continued with CRE's (Creative Research Enterprises's) IR&D resources, until a sponsor is found. Chiu, Y. T. and Prasad, S. S.

Book Synopsis Introduction to Astrochemistry by : Satoshi Yamamoto
Download or read book Introduction to Astrochemistry written by Satoshi Yamamoto and published by Springer. This book was released on 2017-02-13 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important book describes the basic principles of astrochemistry—an interdisciplinary field combining astronomy, physics, and chemistry—with particular emphasis on its physical and chemical background. Chemical processes in diffuse clouds, dense quiescent molecular clouds, star-forming regions, and protoplanetary disks are discussed. A brief introduction to molecular spectroscopy and observational techniques is also presented. These contents provide astronomers with a comprehensive understanding of how interstellar matter is evolved and brought into stars and planets, which is ultimately related to the origin of the solar system. The subject matter will also be understandable and useful for physical chemists who are interested in exotic chemical processes occurring in extreme physical conditions. The book is a valuable resource for all researchers beginning at the graduate level.
