Lab reports for Ex. 1.0 are to
be submitted in the next class following the day when the lab
was done. Reports for other
labs are to be submitted as given below:
Read over Ex. 2.0, which is to be
done at the second lab session. Bring your centimeter
ruler and calculator with you to
lab. You do not have to print an answer page and chart
to bring to lab to do this exercise.
However, you will need to print the answer page for your final
report to be submitted for grading.
Tuesday lab people are to identify only the odd
numbered stars. Friday lab
people are to identify only the even numbered stars plus the
last one, #15, Fomalhaut.
Ex. 2.0 is to be submitted in
the next (3rd) lab session.
Ex. 15.0 will be submitted during the week of Feb. 10 in lab.
Ex. 5.0 is to submitted
in lab, the week of Feb. 23. Include a cove page and the two answer
sheets.
Ex. 7.0 is to be submitted
in lab the week of Mar. 17. Read the LAB INFO
document on what to submit.
Ex. 13.0 is to be submitted in lab during the week of April 01.
Ex. 6.0 is due in lab the week of April 08.
Ex. 14.0 is to be submitted on a date to be annonced
All remaining labs are to be completed in lab and submitted for grading.
Ex. 17.0 is to be submitted in lab on the day it is done.
Ex. 17.1 is to be submitted in lab one week later.
Ex. 18.0
Ex. 18.7
Virtual Astronomy Ex. 21 is to be done
VA Ex. 27 is to be done on a
date to be posted.
See "LAB INFO" for the
schedule of subsequent labs, cover page format,
and other information about
lab and lab reports.
Always come to lab with the answer sheets already
printed, unless informed otherwise,
as is the case for Ex. 2.0.
Read my online documents titled "Time" and "Lunar
Motions & Eclipses. In the latter,
the section on Eclipses should be read in conjunction
with doing Ex. 14.0. Section D
of the "Time" document should be read and applied
to do a calculation in Ex. 13.0.
Homework:
The due dates for any homework assignment will be posted here:
Do Ex. 7.2 for extra credit and sumit.
Start working on Ex. 15.1 after
Kepler's Laws are presented in lecture.
Additional Instructions:
Draw the major and minor axes on each of the three charts that you print.
Read the
online document "Time"
on how to do the necessary calculations and include these
calculations on a separate
page to be submitted as part of your report. Alternatively,
use SKYLAB's program "Animate
Diurnal Motion of the Sun, as you did for Ex. 7.0, to
find the Julian date, JD,
for each chart. Subtract the Julian dates and divide by
365.25 to convert to years
and decimal parts thereof. Do not convert the decimal to
months and days.
Submit Ex. 15.1 on March
25 in lecture by all lab sections.
Make sure the charts are
stapled together facing the correct way.
The answers to the following assignments and
questions are not to be submitted
unless specifically given a due date.
Do assignments 1 thru 8 for test 1, but do
not hand in. Any of these questions
could be on the test.
Do the practice problems 1 A&B below after the first lab, but do not submit.
1. Practice Problems:
A. Calculate how long
it will take the Earth to rotate through an angle of 78 degrees?
First show the answer in hours and decimal parts thereof, then give the
answer in
in hours and minutes, such as, 13.87 in decimal form is the same
as 13: 52 in
sexagesimal form.
B. How many degrees
will the Earth rotate in 8 hours and 25 minutes? First convert
the 25 minutes to the decimal part of an hour, add this to the hours and
then
multiply the sum by the angular rate of rotation of the Earth to get the
answer in
degrees and decimal parts thereof.
Then convert the decimal part of a degree to arcminutes, rounding to the
nearest
arcminute.
Also see examples 2 to 5 in Appendix C in the
Course Manual.
Do the practice problems below after the second lab, but do not submit.
2. Use the four seasonal star charts in
the back of S&A (they follow the index ) to locate
the constellations visible in the evening sky
for the current month Read the instructions for
using the charts. The size of a star
image is indicative of its apparent brightness.
3 Use the foldout, rectangular star chart
at the back of the book for the following:
The constellation Aquila is centered at approximately
RA= 19:40 and Dec.=+5:00. What
is the name of the brightest star in this constellation?
This
question will definitely
be on the test.
4. Estimate the RA and Dec. of the star in question 3.
5. What constellation is centered at RA = 1:30 and Dec. = +44:00?
Study all of the questions at the end of S&A
Unit 5. This material is also covered in
Ex. 1.0, 2.0, 5.0 and 6.0 in my Course Manual.
Study all the questions at the end of S&A,
Units 1, 2 . Any of these may be on
the test.
6 From S&A, Fig 5.9 on page 40, what
large object is centered at approximately
RA=0:38, Dec.= +42:00?
7. From S&A, Unit 6, what is the name
of the bright star that will be near the north celestial
pole in the year 14000 AD? This
question will be on the test.
8. On a piece of paper draw two bodies
whose centers are separated by a line that is
6.00 cm long. Label the bodies as A and
B. If body A is 8 times the mass of B, locate
where the barycenter of the system is located.
The sizes of the two bodies are not
important; you may draw them any size you want.
It is possible for the barycenter to be
inside one of the bodies, depending on how large
you draw them.
For Test 2 on March 7.
9 On the foldout, rectangular star chart
at the back of the textbook, you will find the ecliptic
on which are located the months and days for
the position of the Sun. In what constellation
is the Sun located on October 15? How about
April 30?
10 Do Ex 5.2, but do not submit. This will be on the test
11. Use
the foldout, rectangular star chart at the back of the textbook for the
following:
What is the name
of the bright star located at RA = 2h 20m and Dec.=
-3o? In what constellation
is this star located?
This question will be on the test.
12. Is the star in #11 a circumpolar star for our latitude?
Be able to answer the following questions from
Unit 5 in S&A for test #2: 4, 5, 7, 8, 9,
11, 14, 16, 17, 18 & 19.

Be able to answer the following questions from
Unit 34 in S&A for test #2: 4, 5, 6, 16,
17 & 18.
The following questions will be on the test 3 on April 15, except those in blue:
From Ex. 14.0. When will the next solar
eclipse be visible here? Will this eclipse
be total or partial? Also look at
Fig. 8.9B in S&A. Name 3 contiguous states in which
this eclipse will be a total one (You must know
some geography of the US).
Unit 56.3: Who was the astronomer that,
in 1901, did most of the stellar spectral classification
for the Draper Catalog?
On page 462 of S&A, Fig. 58.1C, what is the diameter of the star Betelgeuse in AU?
A certain star
has an apparent visual magnitude of 7.22, its spectral type is M2 and its
luminosity class is Ia.
A. What is the absolute visual magnitude of this star?
B. What is the distance modulus of this star.
C. What is the distance of this star?
Use the H-R Diagram
on page 473 in S&A or the one at the end of my Chap. 9,
where Lum. Class I is mid-way
between Ia and Ib,
or the one in EX. 18.7.
What is a T Tauri star?
What two physical parameters of a star determines its luminosity?
If you have any questions about the above assignments, come to see me in my office.
Find the star Alnitak in Figs. 59.3 and 59.5,
pages 469-471, in S&A and determine the
following for this star:
The spectral type,
temperature,
luminosity in terms of the
Sun's,
mass in solar units and
luminosity class.
Also from the same diagrams mentioned above, what
is the name of the star that has
a temperature of 8000K and a luminosity of 10
times that of the Sun?
