This book covers the fundamentals of astronomy, such as coordinate systems, transformation of coordinates, measurement of time, telescopes, the black body, flux and magnitude, the cosmic distance ladder, celestial mechanics and Kepler's laws, the motion of planets and transfer orbits. Each chapter contains many exercises and problems to help the readers familiarise themselves with the contents. Part of the questions were selected from more than 10 different National Astronomy Olympiads, the International Olympiad on Astronomy and Astrophysics (IOAA) and the International Astronomy Olympiad (IAO). At the end of the book there are detailed solutions to all the exercises and problems. The only prerequisite is a basic knowledge of high school mathematics and physics. Slightly more advanced mathematical tools are covered in the appendix, making the book self-contained. This book is specifically aimed at students preparing for the regional and national phases of the Astronomy Olympiads, but will also represent a valuable resource for those selected to represent their countries at international competitions.

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. This is the fifth edition of the successful undergraduate textbook and reference work. It has been extensively modernized and extended in the parts dealing with extragalactic astronomy and cosmology. You will also find augmented sections on the solar system and extrasolar planets as well as a new chapter on astrobiology. Long considered a standard text for physical science majors, Fundamental Astronomy is also an excellent reference work for dedicated amateur astronomers.

Astronomy is inherently more observational rather than an elemental study of science. All measurements are performed at a greater distance from the object of interest, with no control of quantities such as chemical composition, pressure, or temperature. You will also understand the study of the solar system with relation to the gravitational attraction that holds the planets in their elliptical orbits around the sun. An early study of the universe was done through the naked eyes. This method led to the categorization of the celestial bodies and assigned constellations. Constellation has been a very important navigational tool since the beginning of the world. Various disciplines of Astronomy will also be discussed. Examples of such disciplines include: - Astrophysics - Galactic astronomy - Galaxy Formation - Cosmology - Astrometry - Extragalactic astronomy - Stellar astronomy - Planetary sciences - Astrobiology - Formation of stars

This invaluable book, now in its second edition, covers a wide range of topics appropriate for both undergraduate and postgraduate courses in astrophysics. The book conveys a deep and coherent understanding of the stellar phenomena, and basic astrophysics of stars, galaxies, clusters of galaxies and other heavenly bodies of interest. Since the first appearance of the book in 1997, significant progress has been made in different branches of Astronomy and Astrophysics. The second edition takes into account the developments of the subject which have taken place in the last decade. It discusses the latest introduction of L and T dwarfs in the Hertzsprung-Russel diagram (or H-R diagram). Other developments discussed pertain to standard solar model, solar neutrino puzzle, cosmic microwave background radiation, Drake equation, dwarf galaxies, ultra compact dwarf galaxies, compact groups and cluster of galaxies. Problems at the end of each chapter motivate the students to go deeper into the topics. Suggested readings at the end of each chapter have been complemented.
