Some information may be deleted or added to this, but this is very close to the formula sheet that will be on the exam.


Textbook

If you have access to the eText (almost all of you will) you may wish to follow instructions to allow you to get chapters onto your
iPad tablet or Android tablet. The prof thinks that if you bus commute a lot, this is an easy way to do readings while travelling.

Homework

See the Course Summary handout (available in Handouts section below) for information on how quizzes and homeworks contribute to the course grade.
Quizzes are done 3 times/week via Mastering Astronomy (see above)
Homeworks will occur about a half-dozen times over the semester, and be posted here.

Follow this link to Homework 1 (due Wednesday Sept 10, at local solar noon by EMAIL).

Homework 2 (Second sunrise/sunset) was distributed by email.

Click on this link to access Homework 3 (PDF file). Due Friday Oct 3, in the ASTR 310 box just outside the entrance to Henn 312 (your tutorial room). You may NOT submit this be email.
SOLUTION OUTLINES
1. You'll get something in the range 0.5-1.0 degrees.
2. Latitude is 30deg3minutes = 30.05 deg north and longitude 31.95 deg east. Cairo is straight west.
3. The physical seaparation is 0.000 137 AU = 20 500 km.

Click on this link to access Homework 4 (PDF file, due Friday Oct 24 5 PM, in the ASTR 310 box just outside the entrance to Henn 312 (your tutorial room). You may NOT submit this be email. CLARIFICATION : The Cassini radar dish is 4.0 meters in diameter.
SOLUTION OUTLINES:
1. The small angle formula provides the major axis to be 40,000 km. The semimajor axis is half this, or 20,000 km. Use Newton's form of Kepler's Third law (assuming the mass of the moon is a neglible fraction of the sum of the two masses, and making sure that P is in seconds and 'a' is in meters) to conclude that the object's mass is 1.6x10^{18} kg. That's only 2.7x10^{-7} of an Earth mass.
2. Need to get the orbital period P, and thus need semimajor axis a. But the perihelion distance 0.812 = a(1-e) = 0.27a so a=3.007 AU. Kepler's 3rd law gives P=5.21 yr. So last perihelion was 5.2 years before 2014 (in 2009) and the one before that was 10.4 years ago (in 2004).
3. The angular separation of the two islands seen from 1200 km is 172 arcseconds. Using 2.2m waves, Cassini's 4.0 m diameter dish has a diffraction limit of about 1380 arcsconds. Since this smallest angle of 1380" is much bigger than the angular separation, they cannot be resolved. [ Prof's comment: One would need to have a dish 10 times bigger to improve the resolution, or fly 10 times closer. Neither are feasible.]



Tutorials

Tutorials will run every other week, except that the first tutorial meeting will be delayed by a week.
Specifically, you will go to your Hennings 318 during your tutorial time slot on the weeks of

Sept 15, Sept 22, Oct 6 and 10 (but Wednesday sections Oct 15), Oct 20, Nov 3, and Nov 17

TA contact information

If you will miss your tutorial, contact your TA ahead of time. If you cannot make posted office hours, contact the lead TA for your section for an appointment.
