- Text problem 8.8
- Text problem 8.9
- Text problem 8.16
- Text problem 9.4
- Text problem 9.6
- Consider observing an asteroid belt around another star, using the
results from the previous problem:
- What is the optimum wavelength for observation? Would this be
better done from space or from the ground?
- What is the surface brightness of the asteroid belt if seen face on?
- Compare the brightness of Earth to that of the integrated
brightness of the asteroid belt at this wavelength (the comparison
is independent of distance, although the individual fluxes are not).
- You wish to independently analyze photometric data to determine
rotation periods of asteroids. Go to the Small Bodies Node of PDS at
http://pdssbn.astro.umd.edu to find appropriate data.
- Choose one asteroid and determine the rotational period.
- Summarize the challenges in trying to find and use these data.
