| Course Description: | The course is concerned primarily with astronomy beyond the solar system. We start by reviewing the properties of light and atoms, and discuss how telescopes and spacecraft are used to observe astronomical objects. We turn then to the Sun as a typical star, concentrating next on other stars and their evolution, how stars are initially formed out of the interstellar matter, and what happens to stars late in their lives (white dwarfs, neutron stars, black holes). We will also study the vast grouping of stars into galaxies, the properties of spiral and elliptical galaxies, and exotic objects like quasars. Cosmology and the early universe will then be considered, concluding with exobiology (life elsewhere). Methods of scientific research in astronomy will be emphasized throughout the course. We will look at deep-sky objects through telescopes, and study the skies with planetarium projectors. Course includes a significant amount of quantitative analysis invoking math and physics. There are three weekly recitation sections of 50 min each taught by Loren Matilsky in Duane D-142 on Tues both at 1pm and 2pm, and on Wed at 1pm. You are registered for one of these and attendance is required. | ||
| Prerequisites: | ASTR 1030 and Calculus I (or equivalent). | ||
| Textbook & Notes: | Cosmic Perspective, 8th ed, Bennett, Donahue, Schneider & Voit, 2017 (required). The course makes extensive use of additional web-based material, and of announcements, that are accessible from the course D2L site and the primary home page at http://zeus.colorado.edu/astr1040-toomre. Copies of lecture slides serving as notes will be web-posted after each lecture. Many assignments will use the extra resources provided by http://www.masteringastronomy.com. You must establish a personal login to that site using an authentication code supplied with your copy of the book; your login from ASTR 1030 should allow you access to this follow-on course. However, you must register with our class on that site, using the class ID of `ASTR1040TOOMRE2018B', since only then will your work on assignments there count for credit. | ||
| Clickers: | Personal "i-clickers" (radio-frequency response devices) are required for you to be able register your answers to various questions and discussions posed in the lectures and recitations. Please register your i-clicker with the myCUinfo site, using the student tab, or via the course D2L site. | ||
| Course Timing: | The course briefly reviews Chapters 1-6, and then turns in detail to Chapters 14-23, and S2-S4 in Cosmic Perspective (8th ed), plus considerable additional material in lectures. The topics are grouped as: |
||
| 1 | Perspective and Astronomy Matter and Energy, Light/Atoms, Telescopes Our Star the Sun |
Chaps 1, 2, 3 |
|
| 2 | Properties of Stars, H-R Diagram, Binaries Lives of Stars (Birth, Main Seq, Red Giants) |
Chap 15 |
|
| 3 | Relativity (Space/Time/Gravity), Degeneracy White Dwarfs, Neutron Stars, Black Holes Our Milky Way Galaxy |
Chaps S2, S3, S4 |
|
| 4 | Other Galaxies, Hubble Law Galaxy Evolution, Quasars, Active Galaxies |
Chap 20 |
|
| 5 | Dark Matter, Large-Scale Structure Cosmology: Creation and Fate of Universe Life in the Universe | Chap 22 Chap 23 Chap 24 |
|
| Exams & Grading: | Your final grade will be based on three in-class mid-term exams counting 45% overall (50 minutes each, closed book and closed notes, plus reminder sheet), the homework problem sets to be turned in counting 20%, and the final exam (comprehensive in content) counting 25% (2.5 hours, closed book and closed notes). All exams and the final will be based on the required readings from Cosmic Perspective and on the content of the lectures. The clicker in-class responses and discussion contributions, plus observing reports, will count for 10%. Regular attendance at both lectures and recitations is essential and required. Collaborative group work is encouraged.
Exam Dates: (all in Duane G-125) Exam 1: Thur Sept 27; Exam 2:
Thur Oct 25; Exam 3: Thur Nov 29; Final Exam (Comprehensive):
Sun Dec 16, 4:30pm-7:00pm.
Each in-class exam will consist of a mixture of
multiple-choice, true-false, and essay and quantitative analysis questions. You
are expected to take all three in-class exams; unexcused absences count
as an `F'. Absences will be excused only for a very good reason (such
as a verifiable illness or emergency), and only when confirmed in
writing not later than one week after the absence. There
will be no makeup exams!

| Observatory Nights: | Eleven nights are scheduled throughout the semester at Sommers-Bausch observatory (shared with ASTR 1020) so that you can work on projects centered on deep-sky objects. Dates: 1: Tues Sept 4; 2: Wed Sept 12; 3: Thur Sept 20; 4: Tues Sept 25; 5: Thur Oct 4; 6: Thur Oct 11; 7: Tues Oct 16; 8: Tues Oct 30; 9: Thur Nov 15; 10: Mon Nov 26; 11: Tues Dec 4. We will use sign up sheets for each night. |
||
| Planetarium: | The class meets in Fiske Planetarium Theater on three occasions instead of in Duane G-125. Thus go directly to Fiske on Dates: 1: Tues Sept 18, 2: Tues Oct 16 and 3: Tues Nov 13. Please do not arrive late, because that will interfere with other people's adaptation to the dark. | ||
| Accessibilty: | Any student with Accessibility Requirements involving communication or exams should talk to the instructor early in semester to request and arrange suitable accommodations. | ||
