Understanding Variable Stars (Cambridge Astrophysics) by John R. Percy (PDF)

Description

This book was first published in 2007. Variable stars are those that change brightness. Their variability may be due to geometric processes such as rotation, or eclipse by a companion star, or physical processes such as vibration, flares, or cataclysmic explosions. In each case, variable stars provide unique information about the properties of stars, and the processes that go on within them. This book provides a concise overview of variable stars, including a historical perspective, an introduction to stars in general, the techniques for discovering and studying variable stars, and a description of the main types of variable stars. It ends with short reflections about the connection between the study of variable stars, and research, education, amateur astronomy, and public interest in astronomy. This book is intended for anyone with some background knowledge of astronomy, but is especially suitable for undergraduate students and experienced amateur astronomers who can contribute to our understanding of these important stars.

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐This may be the best book I have ever read! Certainly in the top 3 or 4. The writing, editing and production quality are all top notch. The technical level is such that well-informed general readers and those with advanced education in the subject will all appreciate it.The general format is to first explain the observational characteristics of each class of variable star and then to outline the physical reasons for the variability. If you know in general what a star is, what galaxies are and how we designate stars by their membership in constellations, you know enough to enjoy this book. OTOH even those with an advanced, but non-specialist background, will learn much. I have degrees in physics and mathematics and a life-long interest in astrophysics but was still disabused of several misconceptions about variable stars.One of the interesting aspects of the book is the way Percy emphasizes the important contributions that amateurs have made and are still making to the study of variable stars, including novae and supernovae.Highly recommended!

⭐was exactly what i expected

⭐Outstanding book thanks

⭐A must have.

⭐This is a standard astronomy textbook on variable stars that has received lots of good/excellent reviews. The book is expensive, but then the book has to pass through the rigorous Cambridge University Press (CUP) review process in order to be published. Having purchased many astronomy books, I have discovered that the CUP do not publish rubbish. Its style can be “dry”, but authoritative.

⭐Guten Tag,das Buch ist an sich ein netter Einstieg in den Zoo der Veränderlichen. Allerdings wird der Titel “Understanding …” nicht erfüllt! Das liegt natürlich letztlich daran, dass es generell höchst schwierig ist, die Prozesse in Veränderlichen zu verstehen. Nichtsdestotrotz werden physikalische Mechanismen “nur” mit einigen Worten erklärt und nicht näher spezifiziert, allerdings sind von Zeit zu Zeit wichtige Verweise gegeben. Einige empirische Relationen werden gegeben und auf die entsprechenden Publikationen verwiesen. Sehr schön finde ich (persönliche Meinung) die Beispielsterne, welche an jeweiliger Stelle kurz erklärt werden. Auch Tabellen mit einigen nennenswerten Sternen des entsprechenden Typs ergänzen den Überblick. Das Buch greift auch oft auf Amateurbeobachtungen zurück und kann damit dem Hobbyastromen, Lehrer wie auch Dozenten an Hochschulen für entsprechende Beobachtungen bzw. Praktikas motivieren.Es ist ein Überblick und der Titel verspricht leider etwas zu viel. Dennoch ist es gut zu lesen und für einen ersten Einstieg empfehlenswert.Beste Grüsse,DS

⭐Clasifica las estrellas variables pero además, tiene un buen resumen de las estrellas no variables.No se detiene en consideraciones teóricas fisico matemáticas (de agradecer) y expone las propiedades de cada tipo de variables accesible a personas interesadas con la astronomía.Se puede leer con algunos conocimiento de Física y Matemáticas (pocos)
