Astronomy H162: Introduction to Stellar, Galactic, and Extragalactic Astronomy

Prof. Krzysztof Z. Stanek

MTWRF 9:30-10:18 a.m. in EL 2003

Here is our syllabus (PDF format).

Out textbook is:

21st Century Astronomy (2nd edition) by J. Hester et al. (you can also use 21st Century Astronomy: Stars and Galaxies, but don't buy both).

We will explore the huge variety of stars, ranging from ultra-dense white dwarfs, neutron stars and black holes, to giant stars, and show how all can be understood within a simple framework. We will then study how stars and interstellar gas and dust assemble to form our Galaxy, which extends over 100,000 light years. We will also show that our Galaxy and others like it are held together by an omnipresent but unseen "dark matter". We will explore the origin of the universe, showing how direct observations lead inexorably to the conclusion that the universe formed in a giant explosion 13 billion years ago. Finally, we will discuss the mounting evidence that most of the Universe consists of "dark energy".
