Time scale of a supernova light curve
Weblight curve, in astronomy, graph of the changes in brightness with time of a star, particularly of the variable type. The light curves of different kinds of variable stars differ in the degree of change in magnitude (i.e., the amount of light flux observed), in the degree of regularity from one cycle to the next, and in the length of the cycle—i.e., the period. Variations in … WebThe diversity of the early time light curves in our sample can be seen in Fig. 13. The light curves have been stretch-corrected and normalized, and shifted to have a coincident t 0.5. …

WebWe investigate the early-time light-curves of a large sample of 223 type II supernovae (SNe) from the Sloan Digital Sky Survey and the Supernova Legacy Survey. Having a cadence of a few days and sufficient non-detections prior to explosion, we constrain rise-times, i.e. the durations from estimated first to maximum light, as a function of effective wavelength.

The ejected material expanded and faded in brightness as time went on, largely as expected. The twin tail it observed in October was a surprise, leading to continued research. In November, additional ultraviolet …
