Quick Summary
Explosive variable stars, also known as eruptive variables, are stars that undergo sudden, dramatic increases in brightness due to violent outbursts. These events, such as novas and supernovas, release a significant amount of energy over a short period. While the brightening is rapid, the subsequent dimming is typically a slower process. These stars are crucial for astronomers as they can serve as "standard candles" to measure vast distances across the universe.123
