PDF-(READ)-An Introduction to the Sun and Stars

Compiled by a team of experts this textbook introduces the properties and evolution of the most immediately visible objects in the Universe stars Designed for elementary university courses in astronomy and astrophysics it starts with a detailed discussion of our nearest star the Sun and describes how solar physicists have come to understand its internal workings It then considers how we study the basic physical properties and lifecycles of more distant stars culminating with a discussion of more exotic objects such as neutron stars and black holes This second edition has a greater emphasis on the physical and spectral properties of stars introducing stellar atmospheres spectral line formation and the role of binary stars in the formation of compact objects Avoiding complex mathematics and generously illustrated in colour throughout this accessible text is ideal for selfstudy and will appeal to both amateur astronomers and undergraduate students.

This is a second edition of a textbook that provides the first comprehensive, easy-to-read, and up-to-date account of the fascinating discipline of archaeoastronomy, in which the relationship between ancient constructions and the sky is studied in order to gain a better understanding of the ideas of the architects of the past and of their religious and symbolic worlds. The book is divided into three sections, the first of which explores the past relations between astronomy and people, power, the afterworld, architecture, and landscape. The second part then discusses in detail the fundamentals of archaeoastronomy, including the celestial coordinates the apparent motion of the sun, moon, stars, and planets observation of celestial bodies at the horizon the use of astronomical software in archaeoastronomy and current methods for making and analyzing measurements. The final section reviews what archaeoastronomy can now tell us about the nature and purpose of such sites and structures as Stonehenge, the Pyramids of Giza, Chichen Itza, the Angkor Temples, the Campus Martius, and the Valley of the Temples of Agrigento. In addition, it provides a set of exercises that can be performed using non-commercial free software, e.g., Google Earth or Stellarium, and that will equip readers to conduct their own research. This new edition features an “augmented reality” framework, which on the one hand enhances the didactic value of the book using direct links to the relevant sections of the author’s MOOC (online) lessons and, on the other, allows readers to directly experience – albeit virtually –many of the spectacular archaeological sites described in the book. This is an ideal introduction to what has become a wide-ranging multidisciplinary science.

While . there is only one star in our solar system, there are billions upon billions of stars throughout our galaxy and exponentially more in the billions of galaxies in the universe.
