Challenging earlier reports that a mysterious object at the heart of the remnants of Supernova 1987A is a rapidly spinning pulsar, scientists at Columbia University announced that the observed object was more likely to be a vibrating neutron star. The debate over the nature of the object began in February when astronomers at the University of California at Berkeley theorized that they were observing an extremely dense pulsar rotating at 2,000 rotations per second. The Berkeley announcement prompted astronomers at Columbia University to argue that the observed bursts of radiation were more likely to emanate from a less dense neutron star that is vibrating at the observed frequency. The Columbia astronomers argued that the vibration theory not only explained the recent observations but also was consistent with previous hypotheses on how neutron stars develop. (W Post, Mar 27/89)
