21. The light curve displays three maxima and minima per cycle. 22. It causes the light curve of RR Lyrae to change from cycle to cycle. 23. When we saw that light curve , everybody was dancing up and down in the hallways, 24. Other researchers have so far failed to detect any periodic modulation in Nereid's light curve . 25. Light curve data on Metis led to an assumption that it could have a satellite.26. The more slowly the light curve declines, the astronomers found, the brighter the supernova was. 27. They often show many superimposed periods, which combine to form an extremely complex light curve . 28. Photometric observations of this asteroid gave a light curve with a period of 13.623 hours. 29. Have only an inaccurate period, estimated based on a fragmentary light curve and inconclusive measurement. 30. In a February 2013 study, 1, 897 observations were used to create a light curve .
