Summary
| Description |
English: There are three main classes of how an object can vary in time: periodic, quasiperiodic, and transient.
Periodic change means there is a regular, fixed pattern to the change. Sunrise and sunset or a blinking pulsar are examples. Quasiperiodic means that there is a pattern, and the change or event happens again and again, but not as regularly, like hurricanes or flashes from hot material around black holes. Transient events are less predictable and often happen only once. Earthquakes and supernovas are transients. These are the hardest to observe because they can be brief and start unexpectedly. If telescopes aren’t looking in the right place, they miss the beginning, or even the entire event. |
