Astrophysics: Physics 204


Lecture meets in room 342 at 9:00am MWF and the lab is (usually) rm. 336 at 2:10 on Tuesday.  

The tests counts as 50% of the grade, 
Exercises and HW count as 15%, 
the Research project as 15% 
and the final exam as 20%

The research project may, with my permission, consist of a term paper researching a topic in astrophysics, but I would rather it be an observational project using archived data or data we collect as part of the class.  It depends on the weather and the long delayed observatory construction whether we can collect our own data.  Due dates on the research project will be announced as we get deeper into the class.

 

Monday January 12  No class
 Tuesday January 13 Lab meets at NSU observatory
Wednesday January 14 Astronomical coordinate systems, star charts, finding objects in SIMBAD
Friday  January 16 Online resources, Sloan Digital Sky Survey. Begin vector mechanics.
-------------
Monday  January 19  Polar coordinates and polar unit vectors, cross products, dot products, angular momentum conservation and Kepler's 2nd Law.
 Tuesday  January 20 computer lab, learning to use Starry Night by finding asteroids.  

Exercise: Asteroid lab handout

Wednesday  January 21 Centripetal force and Kepler's 3rd Law, circular and elliptical orbits. Energy conservation.
Friday January 23 Kepler's 1st law: integrating to get  r(q)
-------------
Monday  January 26 HW work day: do the problem sheet on orbits. This is HW#1 from Kleppner:

Ch 9 - 7,8,9,10

 Tuesday  January 27 Computer lab, JAVA orbit programs (sorry, the compiler isn't installed on all the computer yet but it is available in 2nd floor labs).

 Exercise: modify twobody3.java program to calculate three bodies at the vertices of an equilateral triangle moving on a circle.  It will be unstable!

Wednesday January 28  The solar system, escape orbits, potential energy and bound motion, comets, planets, etc.
HW#2 Chapter 2 problems from Zeilik: 

Ch 2 -2, 7, 9, 14, 16

Friday January 30  No class: Extended Weekend
-------------
Monday  February 2 I was sick and missed this day. The handout was given on Wednesday...

Handout: sample test questions

 Tuesday February 3 Either computer lab or extra-solar planets lab.  We went with the lab! 

Exercise:  the extra-solar planets lab

Wednesday February 4

Blackbody radiation laws and equilibrium temperatures in the solar system.

Friday February 6 Test#1 sample test questions
-----------
Monday  February 9 formation of the solar system: interstellar gas, interstellar clouds, and star formation regions.
