In a recent publication<\/a> in Monthly Notices of the Royal Astronomical Society, an international team of scientists, including PSO researcher Markus Kromer, investigated explosion models for the bright Type II supernova OGLE14-073. With a rise time to peak brightness of 90 days, OGLE14-073 evolved very slowly. In this paper, the authors present explosion models and synthetic light curves and spectra for OGLE14-073. They find satisfactory fits to OGLE14-073 for a pair-instability supernova in a massive progenitor star with an initial mass of 150 solar masses and low metallicity (Z=0.001), making OGLE14-073 to one of the most promising candidates for a pair-instability explosion.<\/p>\n\n\n\n
