An Etymological Dictionary of Astronomy and Astrophysics
English-French-Persian

1) A curve showing the behavior of the light from a → variable star over a period of time.
2) → supernova light curve.

→ light; → curve.

The graph of luminosity as a function of time after a → supernova explosion. The → light curve goes up rapidly to a → peak luminosity, then decays away slowly over time, with different rates, depending on the → supernova type. The temporal evolution of a supernova's luminosity contains important information on the physical processes driving the explosion. The observed → bolometric light curves provide a measure of the total output of converted radiation of → Type Ia supernovae, and hence serve as a crucial link to theoretical models of the explosion and evolution.

→ supernova; → light; → curve.
