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.
Webat the same time. The addition of new high-quality light curves is highly desirable and is under way at several observatories. In the following we will first discuss the light curves … WebThe snowmobile and its rider have a mass of 130 kg. Under the influence of a drive force of 205 N, it is moving at a constant velocity whose magnitude is 4.47 m/s. The drive force is then shut off. Find (a) the distance in which the snowmobile coasts to a halt and (b) the time required to do so. (a) s= (b) t = i i.
