Unit 8.3:
The Doppler
Effect




Sun’s core is extremely hot, and is as dense as lead.
Continuum (continuous spectrum) produced in the core.
Sun’s outer layers (photosphere) are much cooler than the core.
Spectral lines produced in the outer layers of the sun.



See blue shift when light source approaches you.
See red shift when light source recedes/moves away.
Know the equation for the amount of Doppler shift:

Also know the equation for the final (shifted) wavelength:

Unit 7.2:

The H-R Diagram 

Review the locations of main sequence stars, supergiants, giants, and white
dwarf stars on the H-R Diagram.
Spectral class order from hottest to coolest: O, B, A, F, G, K, M.
M-K classes: supergiant (I), normal giant (III), and main sequence (V)
Stars evolve and do NOT last forever. Absolute magnitude and spectral
classification are useful in figuring out how a star will evolve.


Parallax is used to measure the distances to nearby stars.
Know the equation for parallax: d = distance in parsecs, p = parallax in arc
seconds:

Conversion from parsecs (pc) to light-years (ly), 1 pc = 3.26 ly.

Distances
Unit 8.4:
Black Holes

= m + 5 – (5 log D)

The Hubble constant can be used to find the age of the universe.


A black hole can result from the death of a supergiant star.
The event horizon is the boundary that marks the “point of no return” for a
black hole. Also thought of as the size of the black hole.
There is a super-massive black hole at the center of the Milky Way.

II.
Apparent magnitude is how bright something appears in the sky.
Absolute magnitude is the apparent magnitude a star would have if it were
10 parsecs away.
Know the relationship between apparent magnitude (m), absolute
magnitude (M) and distance (D):
