    Astronomy and Astrophysics Notes

    Topics in our Astronomy and Astrophysics Notes PDF

    In these “Astronomy and Astrophysics Notes PDF”, you will study the basic knowledge about the theory and techniques of observational astronomy and physics of the astrophysical phenomenon. It applies theoretical concepts and mathematical techniques students have learnt in their earlier courses to astronomical and astrophysical phenomenon.

    The topics we will cover will be taken from the following list:

    Introduction to Astronomy and Astronomical Scales: Overview of the Night Sky, Diurnal and Yearly motions of the Sun, Stars and Constellations. Size, Mass, Density and Temperature of Astronomical Objects.
