Sarazin is extremely funny and likes to make jokes or ask humorous poll questions in the middle of class. He is also super helpful during office hours. He introduces some extremely high level concepts but is great at presenting them at a manageable level for his students. The lectures and the HWs are the exam, so take good notes and do your homework well. This course involves a heavy discussion of stars, then of stellar remnants (black holes, neutron stars, and white dwarfs), various space explosions, and finally a discussion of cosmology that incorporates a lot of particle physics. You can easily take this class without having taken modern physics, but it would be difficult without any physics background.

Professor Sarazin is so adorable, he is such a sweet dude! You can tell he does his best to keep the class engaged during lectures, and his puns are so pure. Homeworks are super beneficial and graded lightly, exams kinda suck because it's hard/impossible to get partial credit on quantitative problems. Overall loved Sarazin and the course was super interesting.
