Problems

For all assignments, use only 8.5 x 11 inch white paper without serrated edges.
Write on only one side of a page.  If a problem is more than one page long,
staple together the pages of that problem but do not staple together the pages
of different problems.

A two page summary of your paper is due Fri., 9-06-2013.
A five page summary of your paper is due Fri., 9-20-2013.
An eight page version of your paper is due Fri., 10-11-2013.
A ten page version of your paper is due 1.5 weeks after the 8 page version is
returned to you.  This paper will be graded on a 100 point basis

Prepare a presentation of your paper in class.  You may use power point.  You
will be graded by your peers.

Submit problem 2-D.1 (Ex. 1.0) and 3-G.1for grading on 9-13-2013.

Submit problem 2-D.2, 3-C.1  and 3-G.2 for grading on 9-17-2013.  For Ex. 2-D.2,
stars are identified with a Greek letter and a number.  Record both and the
constellation in which the star is located.

Submit problem 5-C.1  and 5-D1 for grading on 9-24-2013.

Submit  6-A.1 on 10-01-2013:   Compute the position of Mars in
its orbit every 10 days starting at perihelion (t=0).  Be careful when using the
arc-cos function: the true anomaly must go from 0 to 360 degrees.  Normalize
r to the perihelion distance in km.  You have to figure out how to do this algebraically
before you write your program.
Provide the following:

1.  A brief description (< 1 page, double spaced) of what you did and how you did it,
     including derving the expression for normalizing r. This description should
     not be in programming, but in terms of the calculations.
2.   A printout of your program with explanatory comments.
3.  Table 1 of input orbital parameters with units.
4.  Table 2 of orbital coordinates t, r, upsilon, x, and y, with units.  Tables must
      have column headers giving units and tables must be captioned.
5.   A full page graph of x versus y with units and a caption.  Make sure the x and
      y scales are the same or you won't see the proper shape of the orbit.  Plot the
      data points as a scatter plot; do not connect the data points with a curve.  Draw
      the major and minor axes of the ellipse and label them.
6.   Also repeat your calculations for Halley's Comet and make a separate graph.

Problem 7-B2 and 7-13 are due Fri, 10-04-2013.

Assignment 7-B1 is due 10-08-2013

Problem 7-C.3 is due 10-08-2013.

Problem 7-E.3 is due 10-15-2013

Problem 6-D1 is due 10-15-2013

Peoblem 7-15 is due 10-18-2013

Problem 7-16 is due 10-22-2013. Submit your program, the graph (properly
annotated and formatted, an additional typed page of your explanation.  Do
not submit any data out put tables.

Problem 7-17 is due Nov. 8
   Rewrite the program you wrote for 7-16 to make it more efficient by
dimensionalizing T as a vector where each value of T is indexed asT(i)
(See my manual).  Then use a Do loop or Dowhile loop to compute the
S-B law and Planck Function for each value of T(i).  This replaces
rewriting the equations 5 times or writing 5 different programs.
Submit:
A cover page
The program
The output Table with 3 columns: T, B and F, properl;y formatted with
caption, which you can add in Word.
No graph is needed.

Submit 8-1, 11-3,  11-5,  11-11 on Nov. 5.

Submit Z&G problem 11-12 and RJP 14-12 on Tues., Nov. 12.  How to do RJP-14
may be found in Z&G Chap. 16 on thermonuclear reactions.

Submit RJP 7-22 on Tues., Nov. 19.  Measure on the chart in cm to 2 decimal places
and maintain this precision all the way to the end.  The wavelengths on the chart are
exact for all intents and purposes, that is, the wavelengths, such as 5800 Ang., have at least
two decimal place precision. Always when determining a chart scale, one measures the largest
distance possible between two fiducial marks in order to average out errors of measurement,
both on the ruler and on the chart.
Calculate the radial velocities in km/s.

Submit RJP 14-22 on Tues.,  Assume the white dwarfconsists entirely of C12 nuclei and
neglect the electrons.  Assume the luminosty of the WD stays constant.  This is
not realistic but otherwise you would have to solve a differential equation.

Submit Z&G Problem 14-6a,b,c on Fri., 12-6.  Label the total mass within radius R, Mtot.
For part b, express the mass within r<R in terms of Mtot.
In part c, first find the circular orbital speed v in terms of r, G, R & Mtot before
finding the angular speed.
