Number 215 (Story #2), February 24, 1995 by Phillip F. Schewe and Ben Stein CHAOTIC PULSATING STAR: Detailed observations of the star R Scuti show that its fluctuating light emissions conform to the mathematical definition of chaos (J. Robert Buchler et al., Physical Review Letters, 6 February 1995). According to Zoltan Kollath of the University of Florida, this is the first strong evidence for chaotic emissions from a star. He and his colleagues assembled data taken over 15 years by numerous astronomers. They deduce from the star's light curve (emission as a function of time) the notion that the complex pulsation variability might result from the overlap of as few as two different vibrational modes in the star.
