Richard,

We now have multiple instances of catching these outbursts in progress
for 29P and 12P. As you say, the shape of the outburst lightcurves
strongly indicate an impulsive release of material which then expands
into the vacuum. The latest example for 29P is a really good example of
this.

Can you explain to us non-chemists why the standard professional model
of crystalline-amorphous ice phase change just can't explain what we
observe.

Scientific theories develop an inertia all of their own but eventually
they have to be abandoned if they don't fit the facts.

Nick.

PS - Jeremy - Thanks for posting these papers. They are often very
interesting and, like this one, are good starting points for other
discussions.
