Overview
Core model: Light Curves, Time-Domain Astronomy & Transients
Time-domain astronomy studies how brightness, spectrum, or position changes with time. A light curve turns repeated measurements into a record of variability, revealing periodic stars, eclipses, transits, flares, supernovae, tidal disruption events, and other transient phenomena.

TESS continuously monitors changing sources in broad sky sectors, while Rubin's LSST repeatedly surveys the southern sky to detect and classify enormous numbers of changing or moving objects.
