Astronomy 10 GOALS & OBJECTIVES Professor David Dunn Office: ST-2 (Outside of Sewell Hall) Phone: 916-781-7162 Email: [email protected] Syllabus Supplement Schedule MA © Sierra College Astronomy Department Extra Credit 1 Overview Student Supplement Handbook (Astro 10 Version) Syllabus and Schedule of Activities ALL third hour activities Informative documents relevant to your grade Also: pick up handouts (Syllabus Supplement and General Schedule of Activities) Web HB-1 site: http://astronomy.sierracollege.edu Nearly all materials can be found here ALL of the lecture presentations found here (eventually) © Sierra College Astronomy Department 2 Overview Third-Hour will be ST-2, which lies on the theatre side of Sewell Hall HB-1 Supplement ST-2 © Sierra College Astronomy Department 3 More Overview While I Take Roll … Complete the Yellow Card! • PUT ASTRO 10 ID# IN YOUR HANDBOOK! (This 4-digit # appears on the upper left hand corner of the yellow card) It is not your Student ID#, nor is it your SSN, not is it the same as any other Astronomy ID# you may receive in another course. This number should be used on all assignments and correspondence with the instructor • You must also choose a 3rd hour … Third Hours for Astro 10 Indicate the 3 choices (by numerical ranking) of 3rd hours you want to attend on the Yellow Card (use the NUMBER !!!!!!) assignment of 3rd hour will be posted by Monday on line and on our bulletin board. Your Try to go to any of the Third hours this week, but then go to one assigned to you next week More Overview Syllabus HB-2 and Schedule of Activities Course consists of two hours of lecture (in S202) and one “third hour” (in ST-2) My “Official” Office Hours (in ST-2) • 11-12 M; 3-4 Tu; 3:30-4:30 W or Anytime my door is “open” or after class Course required materials: • The Essential Cosmic Perspective (text), Astro10 Handbook (Current), 2 Star Maps (SC001, SC002), 2007 Sky Gazer’s Almanac (not available at bookstore) Recommended materials: • • Astronomy Quick Study Guide, The Night Sky Planisphere More Overview CPS device pads (the “clickers”) We will use it for attendance, and weekly quizzes worth 5 points each You will be assigned a clicker which corresponds to you Astro 10 ID We will practice using these things first before the quizzes start CPS = Class Participation System © Sierra College Astronomy Department 7 More Overview HB-3 General Instructor Expectation of Students Students Expectation of Instructor Be aware of deadlines (see handout), safety protocols More Overview HB-3 Grades: See Course Syllabus for more details ! • Point total for class: 500 Must be here for Midterm or Final (or Quizzes) • • • Tests, Homework, Third Hour Assignments, Extra/Bonus Midterm, 2-part 100 pt. Exam Sky Quiz, end of semester, 30 pts. Final, 3-part 110 pt. Exam Grading follows standard 90% and above for an A, 80-89.9% for a B, etc. More Overview Syllabus • • • Supplement and Schedule of Activities Homework is due every week except this week, the weeks of the final and midterm worth 10 pts/week • HB-3 Questions come from Mastering Astronomy website at http://www.masteringastronomy.com 20 or so questions assigned per week Due NOON on Friday (or last non-holiday day of week) LATE HOMEWORK NOT ACCEPTED! See Mastering Astronomy links at our website http://astronomy.sierracollege.edu Third-hour assignments each worth 5 pts/week “Clicker” questions worth 5 pts/week More Overview Syllabus and Schedule of Activities Extra Credit One of two Bonus questions on HW • Extra Credit Options sheet (in Handbook) See General Schedule (Handout) • Other things Penalties for academic dishonesty Check grading accuracy HB-3 Supplement Schedule Overview Extra Credit should be turned in here The White Box © Sierra College Astronomy Department 12 Overview “Secrets” to Success (For a grade of B or A) Do the assigned reading (fast) before the first lecture of the week. Read all the homework questions before the first lecture of the week. Attend lectures with PowerPoint lecture notes from the Student Handbook and CPS devices (“clickers”) Work in groups. Do not wait to the last minute to prepare for exams. Do some extra credit. Ask questions. © Sierra College Astronomy Department 13 Recent events Lunar Eclipse Tuesday morning (about 3 AM) Recent events The Hole in our universe © Sierra College Astronomy Department 15 Recent events USA, Jan 11 Italy, Jan 13 Comet McNaught (C2006 P1) gets near the Sun SOHO site movie South Africa, Jan 17 New “Tenth” Planet: 2003 UB313 and Friend Recent events: Just what is a planet? orbit Xena and Gabrielle Recent events – Just what is a planet? The International Astronomical Union voted to demote Pluto to a dwarf planet Initially a committee defined 12-planet solar system (included Ceres, Charon, Eris [aka “Xena”]) Several groups disagreed and made their own definition which excluded Pluto and the others A vote was taken last August and modified version of second’s groups definition won So for the moment we have eight planets! A little history about the instructor Grew up in Woodland, California Went to UC Davis as undergraduate Majored in Physics Spent 10 years as graduate student at Iowa Was a teaching assistant for most of the time Studied Saturn’s rings for thesis work Then worked as a post-doc/researcher at Berkeley (and still do) Studied these planets using radio telescopes radio More history about the instructor Why my interest in astronomy? Dad and brother built a telescope when I was young Several interesting celestial events happened within 2 years of my initial interest I started to read about it! • Sky and Telescope Goals Acquire An Appreciation of Our Celestial Environment Develop the Needed Skills to Interpret the Observed Sky Gain an Understanding of Astronomers’ Role in Acquiring Information and Formulating Theories About the Universe © Sierra College Astronomy Department 22 Any Questions? © Sierra College Astronomy Department 23 Objectives General Introductory Topics The Celestial Sphere - Equator and Poles Ecliptic and Zodiac Seasons, Eclipses, and Moon Phases Contributions from Past Astronomers Kinematics and Dynamics Laws of Motion Motion Under Influence of Gravity © Sierra College Astronomy Department 24 Objectives Basic Principles of Physics Nature of Light Structure of the Atom and Nucleus Spectra Thermal Processes Ionization Doppler Shifts © Sierra College Astronomy Department 25 Objectives Earth Interior Structure Plate Tectonics Origin of the Atmosphere Greenhouse Effect Seasons Precession © Sierra College Astronomy Department 26 Objectives Moon Surface Features and Origin Eclipses Tides The Solar System Planets Asteroid and Kuiper Belts, Öort Cloud Formation © Sierra College Astronomy Department 27 Mars – Spirit 2004 - 2006 Dust Devils Mars – Opportunity: 2004 - 2005 Saturn from the Hubble Space Telescope Cassini: Mission to Saturn Saturn Huygens probe lands on Titan Titan Objectives The Sun Size and Structure Physics Surface Features Atmospheric Layers Solar Cycle © Sierra College Astronomy Department 32 Different Faces of the Sun UV magnetogram optical X-ray Objectives Basic Stellar Concepts Parallax Magnitudes Luminosity and Temperature The H-R Diagram Mass © Sierra College Astronomy Department 34 Objectives Stellar Evolution Nuclear Burning and Nuclear Synthesis Life Expectancy and Mass Supernova Explosions White Dwarfs, Neutron Stars & Black Holes Pulsars and X-Ray Binaries © Sierra College Astronomy Department 35 Objectives The Milky Way Basic Characteristics and How We Know Location of Our Solar System Nebulae and the Interstellar Medium Origin of the Galaxy © Sierra College Astronomy Department 36 Objectives Other Galaxies Basic Types Theories of Formation Properties of Active Galaxies Hubble Law Dark Matter Problem Galaxy Clusters and Superclusters © Sierra College Astronomy Department 37 NGC 1232 The Andromeda Galaxy (M31) Objectives The Universe Evidence for Expansion Big Bang Theory and the Hubble Constant Microwave Background Radiation Olber’s Paradox The Early Universe and Anti-matter Open vs Closed Universe © Sierra College Astronomy Department 40 Any Questions? © Sierra College Astronomy Department 41 Shorter introduction Objectives (See Handbook) General Celestial Concepts/Astron.
