(READ)-An Introduction to the Sun and Stars: Transcript


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. The Sun and the Stars. The Sun and the Stars. Binary stars:. Most stars are found in binary or multiple systems.. Binary star systems consist of 2 stars which are gravitationally bound with each star.
