Structure
Structure of Light Curves, Time-Domain Astronomy & Transients
Cadence, baseline, photometric precision, filter choice, and alert latency determine which timescales a survey can probe. Some sources vary periodically, others stochastically, and transients may occur once.

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.
