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: 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 2012-12-06 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: A few years ago, a motivation for organizing one more IAU Symposium on star for mation in Grenoble, was the anticipated completion of the IRAM interferometer on the Plateau de Bures, close to Grenoble. This choice was also a sort of late celebration of the genius of Joseph Fourier, born in Grenoble, whose work is the very fondation of in terferometry. At the time when we finally announced the advent of this conference, the first reactions we got from the community were expressions of saturation and even reject, the Symposium being unfortunately scheduled almost simultaneously as two other major meetings on closely related topics, and sponsored by different organizations. A wave of disappointment then reached the organizers. Some of us were enthusiastic enough to help the others overcome their discouragement. Let them be thanked here. There was, indeed, a deeper motivation for organizing this conference. It was to trigger the meeting and communication of physicists and astrophysicists since many of the difficulties met now in understanding the physics of the interstellar medium and its evolution toward star formation are common to several, if not most, other fields of physics. They are assigned to one origin: complexity.

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).

Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth in our understanding of how stars form owes a lot to recent developments in techniques for carrying out infrared and millimeter-wave astronomy. Thus Star Formation and Techniques in mm-Wave Astronomy were natural joint themes for the Fifth EADN Predoctoral Astrophysics School held at the Technische Universität Berlin. The lecture courses by six world-class experts are aimed at postgraduate students and scientists with a non-specialist interest in the field. Topics include molecular clouds, T Tauri stars, OB stars, observation methods in infrared and mm astronomy, as well as high resolution techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding star formation is one of the key fields in present-day astrophysics. This book treats a wide variety of the physical processes involved, as well as the main observational discoveries, with key points being discussed in detail. The current star formation in our galaxy is emphasized, because the most detailed observations are available for this case. The book presents a comparison of the various scenarios for star formation, discusses the basic physics underlying each one, and follows in detail the history of a star from its initial state in the interstellar gas to its becoming a condensed object in equilibrium. Both theoretical and observational evidence to support the validity of the general evolutionary path are presented, and methods for comparing the two are emphasized. The author is a recognized expert in calculations of the evolution of protostars, the structure and evolution of disks, and stellar evolution in general. This book will be of value to graduate students in astronomy and astrophysics as well as to active researchers in the field.
