ASTRONOMY 3150
INTRODUCTORY ASTROPHYSICS
PROJECT LIST
(by topic heading)
THE CELESTIAL
SPHERE & COORDINATE SYSTEMS
1. Object Visibility: Each student selects a celestial object to
find and image with the CCD camera system. Each student will use
resources such as The Astronomical Almanac, The Observer's Handbook, The
Sky (software), and the web based Digital Sky Survey to determine the visibility
of a celestial object and to make finding charts. The object should
be observable in the evening sky during the 1st 3 or 4 weeks of the semester.
PLANETARY MOTION
AND STELLAR SPECTRA
2. Satellite Visibility: Using the "Heavens Above" web site
or other available software, each student will select 5 bright satellites
to view from the observatory. If possible, at least one "Iridium
flare" should be selected for viewing. Extra credit possible for
timing the "Iridium flare" and comparing the time of the actual event to
the predicted time.
3. (alternative) We will observe the possible Leonid meteor
storm
predicted for 2000/2001. Extra credit for recording usable meteor
counts.
4. (alternative) Using the CCD and spectrograph at NGAO, we
will attempt to record and process spectra from stars, emission nebulae,
normal galaxies and AGN. Note: Perhaps use some of this data
in number 10 below.
MEASURING THE CHARACTERISTICS
OF STARS
5. The class will make 3-color off-focus images of the bright stars
used in the colors of stars A1020L lab.
6. (alternative) CCD images of "Barnard's Star" or some other
high proper motion star will be obtained to start an on-going project to
measure the proper motion of the star. (Later Intro. Astrophysics
classes will continue the project.)
7. (alternative) CCD images of a nearby star will be obtained
beginning early in the semester and then re-observed approximately once
a month until the end of the semester (perhaps continuing on into the spring
semester) in order to measure the parallax of the star.
STELLAR EVOLUTION
8. The class will use previous observations of the young cluster
NGC 2362 (t CMa) in U, B, and V and produce
an instrumental (or calibrated) CMD. (Optional: Produce a 2-color diagram
with the calibrated data.)
9. (alternative) The class will observer the SX Phoenicis class
pulsating star, BL Camelopardalis. RA=3:47:19, Dec=+63:22:46, Period =
56 min! V = 13.1 (Perhaps in 2 colors, B & V?)
THE MILKY WAY,
GALAXIES & THE UNIVERSE
10. (alternative) If instrumentation is available (spectrograph),
measure the redshift and/or the rotation curve(s) of a relatively bright
galaxy or galaxies. (Optional: Measure the redshift of a quasar
other AGN.) Note: Perhaps use data from number 4 above.
