Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Although massive stars play many important roles in the universe, their formation is poorly understood. Recently, a class of interstellar clouds known as Infrared Dark Clouds (IRDCs) has been identified as likely progenitors of massive stars and clusters. These clouds are dense (n H 2 > 105 cm-3 ), cold (T

This book was released on 2014-11-03 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents an in-depth, high-resolution observational study on the very beginning of the formation process: the fragmentation of dense molecular clouds known as infrared dark clouds (IRDCs). Using the Submillimeter Array (SMA) and Very Large Array (VLA) radio interferometers, the author has discovered a common picture of hierarchical fragmentation that challenges some of the leading theoretical models and suggests a new, observation-driven understanding of how massive star formation in clustered environments may begin: it is initiated by the hierarchical fragmentation of a dense filament from 10 pc down to 0.01 pc, and the stellar mass buildup is simultaneously fed by hierarchical accretion at similar scales. The new scenario points out the importance of turbulence and filamentary structure, which are now receiving increasing attention and further tests from both observers and theorists.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT High mass stars affect their environments on a large scale. However, the processes behind the formation of high mass stars are still relatively poorly understood compared to their low mass counterparts. Infrared dark clouds (IRDCs) and their cold cores (gravitationally bound cores embedded within the IRDCs) are thought to be the earliest observable stage of high mass star formation. By observing these very young regions we gain insight into the formation of high mass stars. IRDCs were initially found as regions of extended absorption in the midinfrared (MIR). However, identifying IRDCs in the MIR alone can create problems because there is no way to distinguish between IRDCs and minima in the MIR background. In this thesis we use data taken by the Herschel Infrared Galactic Plane Survey to observe IRDCs and their cold cores at wavelengths where they are expected to be seen in emission, i.e. in the far-infrared (FIR).

Download or read book Astrochemistry written by David A Williams and published by Royal Society of Chemistry. This book was released on 2023-02-08 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever wondered if the chemical processes taking place in space could be related to the origins of life? The authors of this book, both experienced astrochemists, embark on a discussion to find the answers to this question and more, and include a general introduction to astrochemistry for chemistry students. They explore chemistry occurring in the universe from its very early beginnings until the present era. Based on our current understanding, astrochemistry is known to occur in interstellar gas, on dust grains and in interstellar ices, in stellar atmospheres and envelopes, in dense star- and planet-forming regions, and on planets and other bodies in planetary systems. Recent observational discoveries supported by remarkable laboratory work emphasize chemical complexity, leading to answers to the tantalizing question: can this complexity be related to the origin of life? This book provides the tools to enable chemistry students to make their own computational investigations of astrochemistry and directs study across the chemical sciences and astronomy. Concentrating on fundamental processes, this book is a useful teaching aid.

Download or read book The New Astronomy written by Nigel Henbest and published by Cambridge University Press. This book was released on 1996-08-28 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: The New Astronomy is a rich kaleidoscope of the finest images of planets, stars, galaxies and the universe. It presents a host of new information, gathered from right across the spectrum: spanning the colourful universe from X-rays, through ultraviolet, visible and infrared, and out to the radio waves. Nigel Henbest and Michael Marten take us on a journey in which we view the variety of the cosmos and its contents through every available window. The first edition of The New Astronomy created a sensation, as no accessible description of modern astronomy had attempted to assemble images from so wide a range. For the new edition there are almost 200 entirely new pictures, selected from the Hubble Space Telescope and orbiting X-ray detectors, as well as from very large telescopes based at Mauna Kea, Hawaii and in the Canary Islands. The new science includes intriguing images from gravitational lenses, which are natural telescopes created by black holes inside other galaxies, and a full description of the latest images of the background radiation of the universe. From the nearby planets to, quite literally, the edge of the observable universe, this book is a brilliant synthesis of all that is new in the astronomy of today. Each object described is displayed in a variety of wavelengths. The non-technical text explains the science behind the objects, and it has been substantially re-written for this second edition.

Book excerpt: Astronomy and Astrophysics Abstracts aims to present a comprehensive documen tation of the literature concerning all aspects of astronomy, astrophysics, and their border fields. It is devoted to the recording, summarizing, and indexing of the relevant publications throughout the world. Astronomy and Astrophysics Abstracts is prepared by a special department of the Astronomisches Rechen-Institut under the auspices of the International Astronomical Union. Volume 43 records literature published in 1987 and received before August 15, 1987. Some older documents which we received late and which are not surveyed in earlier volumes are included too. We acknowledge with thanks contributions of our colleagues all over the world. We also express our gratitude to all organiza tions, observatories, and publishers which provide us with complimentary copies of their publications. Starting with Volume 33, all the recording, correction, and data processing work was done by means of computers. The recording was done by our technical staff members Ms. Helga Ballmann, Ms. Beate Gobel, Ms. Monika Kohl, Ms. Sylvia Matyssek, Ms. Doris Schmitz-Braunstein, Ms. Utta-Barbara Stegemann. Mr. Jochen Heidt and Mr. Kristopher Polzine supported our task by careful proof reading. It is a pleasure to thank them all for their encouragement.
