This book was released on 2008-12-31 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: The publication series of Communications in Asteroseismology (CoAst) is one of the most important international journals in the field of asteroseismology. Asteroseismology is the science concerned with stellar pulsation. Every six months, CoAst publishes a newsletter with papers about the latest results and ongoing research projects. Besides these regular issues, special issues such as conference proceedings or software manuals are published in this series. CoAst volume 155 contains two manuals of software tools dedicated to asteroseismology: the web interface DAS (Database AsteroSeismology) and the software package FAMIAS (Frequency Analysis and Mode Identification for Asteroseismology). Both tools have been developed in the framework of European Helio- and Asteroseismology Network (HELAS), which was founded and is funded by the EU. The aim of the FAMIAS / DAS packages is to enable user-friendly access to state of the art methods for asteroseismology. Successful asteroseismology of stars on the main sequence hotter than the sun is highly dependent on the knowledge of the surface structure of pulsational modes, by means of mode identification. Mode identification can be derived from modeling the luminosity variations of the star in several photometric filters and intensity variations in the profile of absorption lines. FAMIAS is a sophisticated tool for the analysis of spectroscopic and photometric time series to find pulsational modes and the corresponding pulsational quantum numbers: the degree l and the azimutal order m. The database DAS contains a well documented library of light curves and spectroscopic time series data of selected pulsating stars. Together with FAMIAS, it provides a complete package of tools for mode identification to researchers as well as to students, working on the field of asteroseismology. This volume is the printed version of the two manuals and is funded by the EU.

Available in PDF, EPUB and Kindle. Book excerpt: This book tells the story of how, over the past century, dedicated observers and pioneering scientists achieved our current understanding of the universe. It was in antiquity that humankind first attempted to explain the universe often with the help of myths and legends. This book, however, focuses on the time when cosmology finally became a true science. As the reader will learn, this was a slow process, extending over a large part of the 20th century and involving many astronomers, cosmologists and theoretical physicists. The book explains how empirical astronomical data (e.g., Leavitt, Slipher and Hubble) were reconciled with Einstein's general relativity; a challenge which finally led Friedmann, De Sitter and Lemaître, and eventually Einstein himself, to a consistent understanding of the observational results. The reader will realize the extraordinary implications of these achievements and how deeply they changed our vision of the cosmos: From being small, static, immutable and eternal, it became vast and dynamical - originating from (almost) nothing, and yet now, nearly 14 billion years later, undergoing accelerated expansion. But, as always happens, as well as precious knowledge, new mysteries have also been created where previously absolute certainty had reigned.

Download or read book Asteroseismology written by Pere L. Pallé and published by Cambridge University Press. This book was released on 2014-01-13 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of stars has grown significantly due to recent advances in asteroseismology, the stellar analog of helioseismology, the study of the Sun's acoustic wave oscillations. Using ground-based and satellite observatories to measure the frequency spectra of starlight, researchers are able to probe beneath a star's surface and map its interior structure. This volume provides a wide-ranging and up-to-date overview of the theoretical, experimental and analytical tools for carrying out front-line research in stellar physics using asteroseismological observations, tools and inferences. Chapters from seven eminent scientists in residence at the twenty-second Canary Islands Winter School of Astrophysics examine the interior of our Sun relative to data collected from distant stars, how to measure the fundamental parameters of single field stars, diffusion processes, and the effects of rotation on stellar structures. The volume also provides detailed treatments of modeling and computing programs, providing astronomers and graduate students a practical, methods-based guide.
Download or read book Maximilian Hell 1720 92 and the Ends of Jesuit Science in Enlightenment Europe written by Per Pippin Aspaas and published by BRILL. This book was released on 2019-12-02 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Viennese Jesuit court astronomer Maximilian Hell was a key figure in the eighteenth-century circulation of knowledge. He was already famous by the time of his celebrated 1769 expedition for the observation of the transit of Venus in northern Scandinavia. However, the 1773 suppression of his order forced Hell to develop ingenious strategies of accommodation to changing international and domestic circumstances. Through a study of his career in local, regional, imperial, and global contexts, this book sheds new light on the complex relationship between the Enlightenment, Catholicism, administrative and academic reform in the Habsburg monarchy, and the practices and ends of cultivating science in the Republic of Letters around the end of the first era of the Society of Jesus.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the stars is the bedrock of modern astrophysics. Stars are the source of life. The chemical enrichment of our Milky Way and of the Universe withallelementsheavierthanlithiumoriginatesintheinteriorsofstars.Stars arethe tracersofthe dynamics ofthe Universe,gravitationallyimplying much more than meets the eye. Stars ionize the interstellar medium and re-ionized the early intergalactic medium. Understanding stellar structure and evolution is fundamental. While stellar structure and evolution are understood in general terms, we lack important physical ingredients, despite extensive research during recent decades.Classicalspectroscopy,photometry,astrometryandinterferometryof stars have traditionally been used as observational constraints to deduce the internal stellar physics. Unfortunately, these types of observations only allow the tuning of the basic common physics laws under stellar conditions with relatively poor precision. The situation is even more worrisome for unknown aspects of the physics and dynamics in stars. These are usually dealt with by using parameterised descriptions of, e.g., the treatments of convection, rotation,angularmomentumtransport,theequationofstate,atomicdi?usion andsettlingofelements,magneto-hydrodynamicalprocesses,andmore.There is a dearth of observational constraints on these processes, thus solar values areoftenassignedtothem.Yetitishardtoimaginethatonesetofparameters is appropriate for the vast range of stars.

Download or read book Asteroseismic Data Analysis written by Sarbani Basu and published by Princeton University Press. This book was released on 2017-09-05 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of stars and stellar populations, and the discovery and characterization of exoplanets, are being revolutionized by new satellite and telescope observations of unprecedented quality and scope. Some of the most significant advances have been in the field of asteroseismology, the study of stars by observation of their oscillations. Asteroseismic Data Analysis gives a comprehensive technical introduction to this discipline. This book not only helps students and researchers learn about asteroseismology; it also serves as an essential instruction manual for those entering the field. The book presents readers with the foundational techniques used in the analysis and interpretation of asteroseismic data on cool stars that show solar-like oscillations. The techniques have been refined, and in some cases developed, to analyze asteroseismic data collected by the NASA Kepler mission. Topics range from the analysis of time-series observations to extract seismic data for stars to the use of those data to determine global and internal properties of the stars. Reading lists and problem sets are provided, and data necessary for the problem sets are available online. The first book to describe in detail the different techniques used to analyze the data on stellar oscillations, Asteroseismic Data Analysis offers an invaluable window into the hearts of stars. Introduces the asteroseismic study of stars and the theory of stellar oscillations Describes the analysis of observational (time-domain) data Examines how seismic parameters are extracted from observations Explores how stellar properties are determined from seismic data Looks at the “inverse problem,” where frequencies are used to infer internal structures of stars
