Astronomy current events question: giant exoplanet orbit computer simulation

Astronomy 210L, fall semester 2019
Cuesta College, San Luis Obispo, CA

Students are assigned to read online articles on current astronomy events, and take a short current events quiz during the first 10 minutes of lab. (This motivates students to show up promptly to lab, as the time cut-off for the quiz is strictly enforced!)

The close-in, eccentric orbits of gas giant exoplanets may be due to planetary collisions and ejections, based on:
(A) look-back time.
(B) far-infrared imaging.
(C) computer simulations.
(D) gravity wave detectors.
(E) lack of solar flare activity.

Correct answer: (C)
