ASTRONOMY 209 PODCAST
Hosted by Rene Plume · EN
This page contains live, video podcasts of Astronomy 209 (Introduction to Astronomy II - The Cosmos) lectures taught at the University of Calgary. AST209 is a comprehensive, descriptive overview of various aspects of the universe outside the solar system covering topics such as: the history of astronomy, interstellar space, stars, galaxies, black holes, supernovae, and the origins of life and the universe.

ASTR209 - Final Review
Apr 13, 201801:02:26Tap to summarizeIn this, the final lecture of the semester, I attempt to review the main, salient points of the course. Whew! Quite a whirlwind!
Transcribe →ASTR209 - Lecture 23
Apr 10, 201800:55:03Tap to summarizeIn this, the LAST lecture of the semester, we discuss General Relativity and Black Holes.
Transcribe →ASTR209 - Lecture 22
Apr 5, 201800:59:48Tap to summarizeIn this lecture we discuss the final stages of the evolution of low and high mass stars. We also learn about Nova and Supernovae. Finally we talk about Neutron stars and begin a discussion on Black Holes
Transcribe →ASTR209 - Lecture 21
Apr 3, 201801:06:57Tap to summarizeIn this lecture we discuss how a low mass star evolves off the main sequence when it runs out of hydrogen to fuse in its core. We follow its evolution from the Main Sequence to a Red Giant to a Supergiant to a Planetary Nebula to a White Dwarf.
Transcribe →ASTR209 - Lecture 20
Mar 29, 201800:53:25Tap to summarizeIn this lecture we discuss the formation of planets and the discoveries of exoplanets around other stars.
Transcribe →ASTR209 - Lecture 19
Mar 27, 201801:06:50Tap to summarizeIn this lecture we continue to discuss the process of star formation from the fragmentation of a giant molecular cloud, to the collapse of the fragment and the formation of the protostar and disk. We also show where the protostar appears on the HR diagram, and how it evolves onto the main sequence.
Transcribe →ASTR209 - Lecture 18
Mar 20, 201801:13:27Tap to summarizeIn this lecture we discuss the hydrogen spin flip transition that produces radiation at 21cm. We also describe the rich and complex molecular chemistry that exists in "molecular clouds", and how these clouds are intimately related to the formation of stars.
Transcribe →ASTR209 - Lecture 17
Mar 15, 201801:06:08Tap to summarizeIn this class we discuss binary stars and how they are used to determine stellar mass. We then begin to discuss the Interstellar Medium.
Transcribe →ASTR209 - Lecture 16
Mar 13, 2018Tap to summarizeNo podcast today. Camera kept cutting out again.....
Transcribe →ASTR209 - Lecture 15
Mar 8, 201801:12:55Tap to summarizeIn this lecture we discuss the basic properties of stars and the stellar Classification system (OBAFGKM) as well as luminosity classes (I through V). We also investigate the the HR diagram and what it infers about stellar properties.
