Astronomy Olympiad Books

Theoretical Textbooks

An Introduction to Modern Astrophysics 
by Bradley W. Carroll, Dale A. Ostlie.
 
An Introduction to Modern Astrophysics reflects the dramatic changes and advancements in astrophysics that have occurred over the past decade. This is an excellent text book introducing all the essentials of modern astrophysics, in a clear and systematic way. The book is much more theoretical, and full to the brim with useful equations, facts, theorems, definitions, lots of worked examples, plenty of problems to challenge you.  An excellent book to prepare for the International Olympiad on Astronomy and Astrophysics (IOAA).

Astronomy: Principles and Practice 
by A.E. Roy and D. Clarke.
 
The book provides several straightforward mathematical tools, and discusses some simple physical processes that are either involved in the astronomer's tools of trade or concerned in the mechanisms associated with astronomical bodies.
The first six chapters introduce the simple observations that can be made by the eye as well as discuss how such observations were interpreted by previous civilizations. The next several chapters examine the interpretation of positional measurements and the basic principles of celestial mechanics. The authors then explore radiation, optical telescopes, and radio and high-energy technologies.

Fundamental Astronomy 
by H. Karttunen, P. Kröger, H. Oja, M. Poutanen, K. Donner. 

Fundamental Astronomy is a well-balanced, comprehensive introduction to classical and modern astronomy. While emphasizing both the astronomical concepts and the underlying physical principles, the text provides a sound basis for more profound studies in the astronomical sciences. Long considered a standard text for physical science majors, Fundamental Astronomy is also an excellent reference work for dedicated amateur astronomers. The exercises of this book are really helpful for astronomy olympiad.

Schaum's Outline of Astronomy 
by Stacey Palen.

This book is for the beginners of astronomy, but it will give you hundreds of examples, solved problems, and practice exercises to test your skills. I'll suggest this book to those kids who are really interested to take part in the Astronomy Olympiad but haven't read any astronomy textbook before. Although the difficulty level of the problems is easy, it'll help you to have a good starting.

A Problem Book in Astronomy and Astrophysics
Editor: Aniket Sule.

This book contains a compilation of problems and solutions from International Olympiad on Astronomy and Astrophysics (2007-2012). The problems are decorated topic wise, i.e. Celestial Mechanics, Optics and Detectors, Galactic Astrophysics, etc. This book is highly recommended for those who are aspiring to participate in the National Astronomy Olympiad or IOAA. You need to have a clear idea about the astrophysical concepts, then this book will come in handy. 



Astronomy: A Physical Perspective
by Marc L. Kutner

Starting with the simplest objects, Astronomy: A Physical Perspective contains explanations of how and why astronomical phenomena occur, and how astronomers collect and interpret information about stars, galaxies and the solar system. The text looks at the properties of stars, star formation and evolution; neutron stars and black holes; the nature of galaxies; and the structure of the universe. It examines the past, present and future states of the universe; and final chapters use the concepts that have been developed to study the solar system, its formation; the possibility of finding other planetary systems; and the search for extraterrestrial life. This comprehensive text contains useful equations, chapter summaries, worked examples and end-of-chapter problem sets.

Astrophysical Concepts
by Martin Harwit

This classic text presents a quantitative understanding of a range of astrophysical concepts. Emphasizing physical concepts, the book outlines cosmic events but does not portray them in detail. Instead, it provides a series of astrophysical sketches showing how to obtain quantitative insights into the structure and evolution of stars, the dynamics of cosmic gases, the large-scale behavior of the universe, and the origins of life. This book strikes a nice balance between mathematical sophistication and generality, but it can be a little difficult to read in places, particularly for someone without a strong physics background.

Roy and ClarkeAstronomy: Structure of the Universe
by A. E. Roy and D. Clarke

Astronomy: Structure of the Universe is the second textbook written by Roy and Clarke. The introductory companion volume of this book is Astronomy: Principles and Practice. This volume, Astronomy: Structure of the Universe describes the observable features of the universe. The first part describes our Solar System and its members, giving special attention to the Sun, Earth and Moon. The second part treats the nature of matter and its behavior in stellar bodies and interstellar matter under a wide range of physical conditions. The third part discusses our Galaxy in detail before considering external galaxies and ending with questions of cosmology and cosmogony.

An Introduction to Mechanics
by Daniel Kleppner and Robert Kolenkow

This is a classic text on the principles of classical mechanics. The explanations are clear, concise and the examples are illuminating. For 40 years, Kleppner and Kolenkow's text has introduced students to the principles of mechanics.

A Student's Guide to the Mathematics of Astronomy
by Daniel Fleisch and Julia Kregenow

This is another book for the the beginners of Astronomy.  The authors address topics that students find most troublesome, on subjects ranging from stars and light to gravity and black holes. Dozens of fully worked examples and over 150 exercises and homework problems help readers get to grips with the concepts in each chapter. An accompanying website features a host of supporting materials, including interactive solutions for every exercise and problem in the text and a series of video podcasts in which the authors explain the important concepts of every section of the book.

Mathematics Olympiad Sample Problems

Figure 1
I. The Figure 1 shown is a square with quarter circles drawn from two adjacent corners. If the side of the square is 16, find the area of the largest circle that can be inscribed in the blue region.

Solution
Let O be the center of the circle and r be the radius of the circle.
The circle must touch the arc AC and BD. Let extended DO touch the arc AC at P.
DP= 16 as it is the radius of the quarter circle ACD.
OP=r,    DO=10-r.
Radius from center O is perpendicular bisector of DC.
So by Pythagoras theorem we can write,
r²+8²=(10-r)²
20r=36
r=1.8
So area of the circle=π(1.8)²

II. There are 20 questions in an exam and you must answer 12 questions including at least 5 questions from the first 6. How many different combinations of questions can you choose to answer?

Solution
Let's imagine two scenarios. In first scenario you chose to answer all of the first 6 questions and in second scenario you chose 5 questions out of the first 6 questions.
If you choose to answer the first 6 questions, there are 146=3003 ways to answer the remaining 6.
If you choose to answer 5 questions from the first 6 questions, there are 65=6 ways to choose them.
Remaining 7 questions can be chosen in 147=3432 ways.
So, 3003+3432×6=23595 ways of choosing 12 questions.
