26-4 = conceptual question from reading chapter 26, section 4

1General Relativity and Expansion of Universe

Curved space (33-3)

Rate of clocks running (Astro #15,16)

Black Holes (33-3) find Schwarzschild radius, do gravitational time dilation. (like the noteguide, PQ33.1#5)

Red Shift (PQ33.1#3)

Hubble’s Law (33:25)

2. H-R Diagrams and star types

HR Diagrams (general) (33-2) H-R Diagrams

Define Types of objects (33-2) (Pulsar, white dwarf, red giant, quasar, black hole, brown dwarf, black dwarf)

H-R Diagrams (33:34)

Spectral type/Dark line spectra (from lecture, Read 27-11 on p. 771 (esp. last paragraph on the page) - really read it. No one gets this question right)

3. Stars and brightness

Magnitudes (Astro:8-10) Apparent Magnitude Absolute Magnitude

Distance to stars and brightness (Astro:11-12)

HR Diagrams, brightness and distance (Astro:13-14) H-R Diagrams at 8:04

Parallax question (33:2 (2.6 pc)) (Calculate parsecs, and convert to meters)
