POSSIBLE GRAVITATIONAL COLLAPSE INTO A BLACK HOLE OF THE PULSAR IN SUPERNOVA 1987A

We discuss how recapture of an object from debris spewed at the early stage of formation by the millisecond pulsar whose signals where observed briefly in the remnant of SN1987A may have caused its subsequent collapse into a black hole, by damping the rapid rotation which is believed to have contributed to its stability. The mass of the object sufficient to bring this about in the two week interval between observation and next search is calculated to be up to 1/20 of a Jupiter mass.
