EAPS 105 HW 10 EXAM QUESTIONS
WITH CORRECT ANSWERS
In Wikipedia, look up "Methods of detecting exoplanets", read the intro and then scroll
down to "Transit photometry", and answer the following question: To find exoplanets,
how does the transit detection method work? - Correct Answers -If a planet crosses in
front of its parent star, then the observed visual brightness of the star drops by a small
amount.
In Wikipedia, look up "Methods of detecting exoplanets", read the intro and then scroll
down to "Transit photometry", and answer the following question: Which of the following
are weaknesses of the transit detection method? - Correct Answers -d. All the above
In Wikipedia, look up "Methods of detecting exoplanets", read the intro and then scroll
down to "Radial velocity", and answer the following question: To find exoplanets, how
does the radial velocity detection method work? - Correct Answers -A star with a planet
will wobble in response to the planet's gravity, causing it to change the speed at which it
moves toward or away from the Earth.
In Wikipedia, look up "Hot Jupiter" and answer the following question: What is a hot
Jupiter? - Correct Answers -A gas giant like Jupiter that orbits extremely close to its
star.
In Wikipedia, look up "Lava planet" and answer the following question: Which situations
might generate a lava planet? - Correct Answers -All the above
In Wikipedia, look up "Super-Earth" and answer the following question: What is a super-
Earth? - Correct Answers -An exoplanet with a mass higher than Earth's, but
substantially below those of an ice giant.
In Wikipedia, look up "Doppler effect" and answer the following question: With the
Doppler effect, what changes when there is relative motion between the source of a
wave and the observer? - Correct Answers -The frequency of the wave
In Wikipedia, look up "Methods of detecting exoplanets", read the intro and then scroll
down to "Radial velocity", and answer the following question: What can only be
determined by combining observations from the radial velocity method with
observations from the transit detection method? - Correct Answers -The mass of the
exoplanet
