This page will contain links to the presentations and activities done in the lectures, discussion sections, and observing sessions. These will only represent a portion of material covered in the lectures.

Observing and discussion sections

Week 1: Sky Tour. Related information - This week's Sky at a Glance from Sky and Telescope magazine online. Blog posts explaining Why do stars twinkle? and another Why do stars twinkle?

Week 2: Information about and expectations for class assignments discussed during the first discussion section meetings. Math Review workshop: practice problems and lecture notes. I will almost never circulate my own lecture notes, but am sharing these because a number of students missed the review because of a conflict. Use these at your own risk and please don't ask me to translate them; they are unedited and messy but are a faithful representation of all topics covered at the review session.

Lectures

Monday, Aug 31: Using your body to measure angles in the sky, measurement uncertainty

Friday, Sept 11: Thought questions about star motion through the Sky; Simulation of motion of the stars

Monday, Sept 14: Announcements. Although we won't use it in class, you may find the simulation of motion of the Sun throughout the year helpful.

Wednesday, Sept 16:Announcements. 3D simulation of Moon Phases. A few PPT slides about eclipses, or in .pdf format

EXAM 1

Monday, October 5: some ppt slides about how astronomers do astronomy. ONLY WORKS ON A MAC.

Monday, October 19: some ppt slides about spectra. Also in pdf.

Wednesday, October 21: Announcements

Friday, October 23: Luminosity function of stars - the x-axis of this figure is "apparent magnitude". Recall that the magnitude system is backwards: higher apparent magnitudes = fainter. Apparent magnitude = 15 ~ 10^-4 times the luminosity of the Sun. Apparent magnitude = 0 ~ 100 times the luminosity of the Sun.

Astronomer's periodic table from textbook, Chemical composition of the Sun, Figure 13.7 from textbook on blackbody radiation.

Monday, October 26: HR diagram one and HR diagram two

Wednesday, October 23: Movie about the Sun - Chapters two and three of the Sun episode of The Universe series from the History Channel. Can be found on youtube as well: Part I and Part II and the first 3.25 minutes of Part III

Monday, November 2: Announcements

Article about the solar neutrino problem.

Some images of Super-K and SNO neutrino experiments: in pdf and in ppt format.

Super HR diagram, that shows temperature, luminosity, radius, lifetime, and main sequence star mass.

Wednesday, November 4: Announcements
