Guiding the reader through all the stages that lead to the formation of a star such as our Sun, this advanced textbook provides students with a complete overview of star formation. It examines the underlying physical processes that govern the evolution from a molecular cloud core to a main-sequence star, and focuses on the formation of solar-mass stars. Each chapter combines theory and observation, helping readers to connect with and understand the theory behind star formation. Beginning with an explanation of the interstellar medium and molecular clouds as sites of star formation, subsequent chapters address the building of typical stars and the formation of high-mass stars, concluding with a discussion of the by-products and consequences of star formation. This is a unique, self-contained text with sufficient background information for self-study, and is ideal for students and professional researchers alike.
Many of the ISO observers who assembled for this workshop at Ringberg c- tle met for the third time in the Bavarian Alps. At two previous meetings in 1989 and 1990 surveys were only a minor topic. At that time we were excited by the discoveries of the IRAS survey mission and wanted to follow it up with pointed observations using an observatory telescope equipped with versatile instruments. With the rapid development of detector arrays and stimulated by ISO’s Observing Time Allocation Committee, however, surveys eventually became an issue for the upcoming mission. In a review paper on “Infrared S- veys - the Golden Age of Exploration” given at an IAU meeting in 1996, Chas Beichman alrea...
This volume contains the proceedings from the conference "The Labyrinth of Star Formation" that was held in Crete, Greece, in June 2012, to honour the contributions to the study of star formation made by Professor Anthony Whitworth of Cardiff University. The book covers many aspects of theoretical and observational star formation: low-mass star formation; young circumstellar discs; computational methods; triggered star formation; the stellar initial mass function; high-mass star formation and stellar clusters. Each section starts with a review paper, followed by papers discussing recent theoretical and observational work. This volume summarises our current understanding of star formation and is useful for both graduate students and researchers alike.
Why did Ptolemy's theory cause problems for the church?What is the big secret concerning the "Age" of the earth?Why do many scientists reject the use of design in explaining origins?The seemingly absurd idea that all matter, energy, space, and time once exploded from a point of extreme density has captured the imagination of scientists and laypersons for decades. The big bang has provided a central teaching for the eons of time of "cosmic evolution", undermining the history and cosmology of the Bible.It is a theory that fails, even violating the very physical laws on which it is purportedly based.In this easy-to-read format, authors Alex Williams and John Hartnett explode this naturalistic explanation for the universe, and show that the biblical model provides a far better explanation of our origins. This fully indexed, illustrated analysis of the big bang theory is an invaluable help in understanding and countering a world view that is as chaotic and destructive as its name implies.
As the dominant star in our sky, the Sun has been alternately worshipped as a god and viewed as a threat over the course of human history. Despite significant advances in astronomy, the Sun continues to surprise us, most notably in its production of so-called "space weather" that impacts technology here on Earth. This unique mixture of familiarity and mystery has made the Sun a main character in popular media over the past three centuries. This book examines how popular media have adapted to our ever-changing understanding of the inner workings of the Sun. It provides a valuable way to observe the inherent problems of communicating science to a non-technical audience. Chapters cut through the widespread hype found on the Internet, and instead explore our ever-improving scientific exploration of the Sun, the persistent misconceptions surrounding it, the fate of the Sun (and its relation to the fate of the Earth) and why, despite comments to the contrary by Oscar Wilde, the average person should care about sunspots.
From the fiery mass of the Sun's core to the black hole at the centre of the Milky Way, Universe takes you on the ultimate guided tour of the cosmos. Full of stunning out-of-this world images reflecting recent advances in space imagery, you'll go on a journey from our solar system all the way to the farthest limits of space. This new edition has been expanded and updated to include the most exciting new discoveries from water on Mars to planets in other solar systems plus up-to-date charts and information on the latest equipment for studying the wonders of the universe. The comprehensive night-sky atlas covers all the constellations and planetary charts showing their positions right up to 2019. With a special embossed jacket, Universe is a beautiful gift for keen amateur astronomers as well as a great reference book for the whole family.

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.
