| Popis: | The neutrino burst from supernova 1987A detected by Mont Blanc, Kamiokande, IMB and Baksan have been studied within 0.01 ms to 1 ms by Ferraz-Mello technique to find periods from uneven spaced data. It is found that only Kamiokande and IMB neutrino data have significant periods 0.499 ms and 0.568 ms, respectively. Our analysis suggest that the supernova 1987A contains a submillisecond pulsar and is supported by the recently discovered submillisecond period detected from supernova 1987A optical data. We suggest that the pulsar in supernova 1987A is a radially pulsating neutron star. |
