👉 In astronomy, an auroral region is a region of space where sunlight can be absorbed by charged particles in the form of electrons or protons. These particles are known as auroras, and they are most commonly seen when there is high solar activity, such as when there is a coronal mass ejection (CME) event. The term "aurivorous" refers to the idea that these regions attract and retain large numbers of stars and planets in their orbits around the Sun.
