Light Curves, Time-Domain Astronomy & Transients: Observation, Measurement & Evidence

Time-domain astronomy studies how brightness, spectrum, or position changes with time. Time-domain data discover exoplanets, supernovae, variable stars, compact-object events, near-Earth objects, and unexpected phenomena.

Different physical processes create characteristic time signatures: orbital geometry produces eclipses, stellar oscillations create pulsations, explosions produce rise-and-decay curves, and rotating spots modulate brightness.
