There was an interesting paper presented at the last NACAA {National
Australian Convention of Amateur Astronomers} in 1996. The paper suggested
SNII type supernova might be enhanced by between 5-70 times normal supernova
rates in galaxies that have had recent bursts of star formation. In
particular galaxies that show a high atomic to molecular hydrogen gas mass
ratios. The paper talked about spirals in particular and I can't remember if
ellipticals were mentioned.
An observing group was set up to monitor about 100 Sbc-Sb spirals to test
the hypothsis.
The chap organising the work was Ian Wilson in the Brisbane Astronomical
Society. If your interested I can chase up his email address

Peter Lowe.
Frankston Astronomical Society

ps. This is the first time I've sent anything to this chat group. If I've
sent it to the wrong address.. I apologise.
