Course Goal / Objective
The aim of this course is to understand the accretion mechanism, which is known to make a significant contribution to the total radiation of such systems, by focusing on close binary systems containing tight objects and celestial bodies such as active nuclei, with the help of basic physics and astronomy knowledge.
Course Content
Covers accretion as an energy source, gas dynamics, the concept of plasma, and the accretion mechanism in binary star systems
Course Precondition
There is no prerequisite for the course.
Resources
Accretion power in Astrophysics Yazarlar: J Frank; A King ve D Raine; Cambridge University Press.
Notes
Open database and related books.
