[vsnet-alert 131] Re: trouble in the jungle



Joe,
Just to point out that your email about TOADs, while informative,
did indeed have a few likely errors.
The TOADs are indeed object which MUST have different physics in their
outburst mechanisms (see Howell et al ApJ 1995, 439, 337 and other
model calcs by John Cannizzo). whether this 'change'
in outburst physics difference happens JUST at 6 mags or not
is indeed not known, but it is NOT needed at 5 mags and IS needed at 7-10
mags.

Also, the TOAds are NOT just like SU UMa stars with bigger outbursts,
The types of outburst (ie, shape and length and frequency) are
different, The TOADs show large velocity winds at maximum ,
and there appears to be both superoutbursts and intermediate outbursts,
as well as rare normal outbursts in soem TOADs.

as for the name not relating to the actual animal representation, I believe
we could name hundreds and hundreds of cases where acyronyms do not
relate to the item they are representing.

So I think it is NOT fair to simply dismiss TOADs nor place them into
the bin of "just non-typical SU UMa stars"
