OAS351 Space Science Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
To outline the space environment and their effects.
To extend the origin of universe and development.
To classify the galaxies and their evolution.
To interpret the variable stars in the galaxies.
To explain theory of formation of our solar system.
UNIT I INTRODUCTION
Introduction to space science and applications – historical development – Space EnvironmentVacuum and its Effects, Plasma & Radiation Environments and their Effects, Debris Environment and its Effects – Newton’s Law of gravitation – Fundamental Physical Principles.
UNIT II ORIGIN OF UNIVERSE
Early history of the universe – Big-Bang and Hubble expansion model of the universe – cosmic microwave background radiation – dark matter and dark energy.
UNIT III GALAXIES
Galaxies, their evolution and origin – active galaxies and quasars – Galactic rotation – Stellar populations – galactic magnetic field and cosmic rays.
UNIT IV STARS
Stellar spectra and structure – stellar evolution – Nucleo-synthesis and formation of elements – Classification of stars – Harvard classification system – Hertsprung-Russel diagram – Luminosity of star – variable stars – composite stars (white dwarfs, Neutron stars, black hole, star clusters, supernova and binary stars) – Chandrasekhar limit.
UNIT V SOLAR SYSTEM
Nebular theory of formation of our Solar System – Solar wind and nuclear reaction as the source of energy – Sun and Planets: Brief description about shape size – period of rotation about axis and period of revolution – distance of planets from sun – Bode’s law – Kepler’s Laws of planetary motion – Newton’s deductions from Kepler’s Laws – correction of Kepler’s third law – determination of mass of earth – determination of mass of planets with respect to earth – Brief description of Asteroids – Satellites and Comets.
TOTAL: 45 PERIODS
