A fresh galactic theory. The burst of neutrinos from a type 2 supernova when impacting a neutron star should give some nuclear fireworks. At the beginning of 1998, the notion that nearby white dwarfs might produce a detectable responce occured. The time of such a burst caused by supernova 1987a is found by calculating the angle between 1987a and the star and multiplying the distance to the star in lightyears by (1-cos a). The delay is taken from feb 21 1987. From the batse 4b catalogue nothing for Procyon B but event 5079 on 96-02-29 was possible for 40 eridani B. A ten degree error radius made it unpromising but it was within a 14 day time bracket. (distance from HIPPARCOS, s&t mar 1998 pg 26.) Then found details of LP532-81. Calculated time for burst oct 1995 plus & minus 5.2 months, possible match with event 3914 95-11-20. Just outside 6.23 error radius. More "iffy" than 40 eridani but taken together on a linear scale, proof may have edged over 50%. Am bound to put these findings forward as Van Maanen's star may burst in mar 2001. (s&t 1983 nov pg 432.) Suggest matching bursts with neutrinos from historical supernovae hitting known dwarfs within 1000 lightyears. And if rationalysing units to prevent confusion, hope this shows the lightyear is practical as well as descriptive . Retire the parsec.
