This book presents a detailed pedagogical account of the equation of state and its applications in several important and fast growing topics in theoretical physics, chemistry and engineering. This book is the storv of the analysis of starlight by astronomical spectroscopy. It describes the development of the subject from the time of Joseph Fraunhofer, who, in 1814, used a telescope-mounted prism to observe the spectral light emitted from several bright stars. He discovered that light was missing at certain colours (wavelengths) in the starlight, and these so-called spectral lines were subsequently shown to hold clues to the nature of the stars themselves. The book explains how the classification of stars using their line spectra developed into a major branch of astronomy whilst new methods in astrophysics made possible the approximate quantitative analysis of spectral lines in the 1920s and 1930s. After the Second World War these techniques were considerably improved when computers were programmed to model the structure of the outer layers of stars. Basic concepts in spectroscopy and spectral analysis are also covered and. finally. Dr Hearnshaw comments on the stellar spectroscopy of some individual star.

First published in 1986, this is the story of the analysis of starlight by astronomical spectroscopy. Beginning with Joseph Fraunhofer's discovery of spectral lines in the early nineteenth century, this new edition continues the story through to the year 2000. In addition to the key discoveries, it presents the cultural and social history of stellar astrophysics by introducing the leading astronomers and their struggles, triumphs and disagreements. Basic concepts in spectroscopy and spectral analysis are included, so both observational and theoretical aspects are described, in a non-mathematical framework. This new edition covers the final decades of the twentieth century, with its major advances in stellar astrophysics: the discovery of extrasolar planets, new classes of stars and the observation of the ultraviolet spectra of stars from satellites. The in-depth coverage makes it essential reading for graduate students working in stellar spectroscopy, professional and amateur astronomers, and historians of science.

Sharon M. Draper presents “storytelling at its finest” (School Library Journal, starred review) in this New York Times bestselling Depression-era novel about a young girl who must learn to be brave in the face of violent prejudice when the Ku Klux Klan reappears in her segregated southern town. Stella lives in the segregated South—in Bumblebee, North Carolina, to be exact about it. Some stores she can go into. Some stores she can’t. Some folks are right pleasant. Others are a lot less so. To Stella, it sort of evens out, and heck, the Klan hasn’t bothered them for years. But one late night, later than she should ever be up, much less wandering around outside, Stella and her little brother see something they’re never supposed to see, something that is the first flicker of change to come, unwelcome change by any stretch of the imagination. As Stella’s community—her world—is upended, she decides to fight fire with fire. And she learns that ashes don’t necessarily signify an end.

This is a book about the physics of stars and starlight. The story of starlight is truly fascinating. Astronomers analyze and interpret the light from stars using photometry and spectroscopy, then inspirational detective work combines with the laws of physics to reveal the temperatures, masses, luminosities and outer structure of these far away points of light. The laws of physics themselves enable us to journey to the very center of a star and to understand its inner structure and source of energy! Starlight provides an in-depth study of stellar astrophysics that requires only basic high school mathematics and physics, making it accessible to all amateur astronomers. Starlight teaches amateur astronomers about the physics of stars and starlight in a friendly, easy-to-read way. The reader will take away a profoundly deeper understanding of this truly fascinating subject – and find his practical observations more rewarding and fulfilling as a result.

Part of a new core curriculum for non-science majors beingdeveloped at New York University. Covers light as a wavephenomenon, spectra, diffraction, Doppler effect, and theories about the universe.
