Exam 7: The Formation of Planetary Systems

The figure below shows data from the transit study of a star in which three different planets (A, B, and C) repeatedly transit in front of the star.Which dip is (are) caused by the transit of the planet with the smallest radius?

Based on the figure shown below, which planet(s) is (are) most likely to have the largest fraction of its (their) mass made of highly volatile materials such as methane and ammonia?

When you push your palms together and rub them back and forth, you are demonstrating one way of converting ________ energy into ________ energy.

Using the Doppler effect data for a particular star shown in the figure below, and assuming the star is about the same mass as our Sun, what is the approximate orbital distance of its exoplanet?
