Good presentation, Yan! There was a lot covered in the 2 days of meetings, and your discussion fit in well. - c ________________________________________ From: Yan Fernandez [yrf@me.com] Sent: Wednesday, August 04, 2010 5:58 PM To: sbag.population@pc93.lpi.usra.edu Subject: Re: [SBAG Population Identification & Characterization] sbag roadmap - first draft at population outline Hi Will -- Thanks for the feedback, yeah I agree with you, I should've made the hot/cold distinction. Also -- Josh, thanks for your comments earlier as well. I mentioned some of those points in the SBAG discussion today. Several people in fact also independently brought up the idea that smaller objects are different, and that we have to define what 'small' is! All this is great stuff to include and elaborate on in the actual section of the Roadmap that we'll wind up writing. By the way, I'm guessing that the slides I showed today to SBAG will appear on the SBAG website soon, for all to see. Otherwise I'll send the file around to the list. cheers, and thanks. --Yan -- Dr. Yan Fernandez, Asst.

The only comment I have is that it's pretty clear that Cold Classical TNOs are quite distinct from hot classical TNOs, so they really ought to be a different group in the outline. Whether hot classical and resonant objects ought to be similarly split is less clear-cut to me, but at least the Cold Classicals really ought to get treated separately Of course, this then raises questions about whether or not important distinctions lurk among Centaurs and ecliptic comets in terms of those having originated in the Cold Classical belt versus others that formed closer in... --- Will
