Re: [meteorite-list] CAI and chondrules

I've my own collection of ideas as to how chondrules developed but will save them for later. As to CAIs and their presence in carbonaceous meteorites. A list member and I had this discussion some time ago and the answer may lie in a process in the "T-Tauri" stage of stellar evolution. When th

Hi All, I think Jeff's answer was definitive in a boomerang way. But wait there's more: http://geosci.uchicago.edu/~grossman/MSD05.pdf I studied this and other articles looking for the same answers as those in the initial post. I'm still looking. The best I can do in my talks is to quote Don

Re: [meteorite-list] CAI and chondrules

Hi, Carl, Francesco, Jeff, List, Wrong, Carl. A good solid "We don't know crap about this yet; it's all up in the air" is the best kind of definitive answer. There are probably a half-dozen scenarios for how this data came about and there's few reasons to choose any one over the others. I was g

Re: [meteorite-list] CAI and chondrules

I didn't say "we don't know cr*p"... I said there was not a definitive answer. We know a lot about the timing, materials, and physical conditions needed to make chondrules and CAIs, and people have used these to make models for their formation. But many of these constraints are under scruti

Re: [meteorite-list] CAI and chondrules

All I mean bu "we don't know, er, stuff..." was that there is no definitive answer to the puzzle. Proof of double supernovae, T Tauri firestorms, system-wide lightning bolts, or demons that like torment human geophysicists is still unavailable. Sterling K. Webb ---

Re: [meteorite-list] CAI and chondrules

From my layman´s perspective and point of view: isn´t it interesting to note that there is still **so much** controversy over chondrule formation, those little round objects which are so evident and very clearly visible in many of the meteorites in our collections, while at the very same time al

[meteorite-list] It's Raining Rocks!

No, not meteorites like Holbrook. And not on Earth. On another planet altogether. The only flaw in their reasoning (the computer model) is the assumption of locked rotation with the star. As a body spirals in toward a much more massive body, it passes into the period of 3:2 resonant locked rotat

Re: [meteorite-list] CAI and chondrules

The origin of chondrules is one of the outstanding problems facing meteorite researchers. There is significant disagreement even among colleagues who routinely work together on this problem. But be aware, nearly everything I say below will be disputed by some folks in the field, each h
