Astro 154 = Galactic and Extragalactic Astronomy, Winter 1989

=================== An updated course outline ===================


Week 5  (Feb. 6, 7, 8):

	Dynamical time scales.  Star clusters and their evolution.
	Dynamical friction.  Ages of globular clusters and the disk.
	Galactic Bulge, and the Halo.

      	(This will be mainly on the globular clusters dynamics and
         evolution.  Covered more than adequately in BT 4.0 - 4.4, 
      	 5.2, 7.0 - 7.3, most of chap. 8.  We will also use many good
      	 rewiew papers on these subjects, esp. by Ivan King.)

Week 6  (Feb. 13, 14, 15):
	Stellar luminosity and mass functions.
	Star formation history, bimodal star formation, IMF.
	(Maybe: Chemical evolution of the Galaxy.)

      	(Some luminosity, mass function stuff is in MB chap. 4,
      	 but mostly we will work from rewiew papers.)

Part II.  Extragalactic Astronomy.
----------------------------------

(This is unchanged as of last time, and is likely to change somehow.
 We will probably need some extra lectures, to be scheduled after the
 midterms.  Please think about possible time slots.)

Week 7  (Feb. 20, 21, 22):
	Classification, morphology, Hubble seq.  Catalogs.
	Variation of properties along the Hubble seq.
	Galaxy luminosity function.

Week 8  (Feb. 27, 28, Mar. 1):
	Manifold of galaxies, parameter correlations, scaling laws.
	Galaxy clusters.  X-ray gas.
	Large-scale distribution of matter.

Week 9  (Mar. 6,7,8):
	Elements of galaxy evolution.
	Mergers and starbursts.  IRAS galaxies.
	Active galactic nuclei.
