    Star and Planet formation with the Spitzer Space Telescope
    from 11 Jul 2005 through 29 Jul 2005

NOTE: On July 25, there will be a co-I meeting to discuss the CY06 Budgets

NOTE: On July 25, there will be a co-I meeting to discuss the CY06 Budgets and CY06 Team Meeting.


General plan:

The main goal is to write papers, which implies that people should stay as long as possible and leaders in certain areas should assemble the teams that need to interact.


The secondary goal is to keep everyone informed about crosscutting science issues. To achieve this, we will start each day with a plenary session (9:30-11:00) on a topic or topics and end with a plenary session (4:00-5:30) reporting progress and new issues.



Each week will have two coordinators, who will set up the detailed agenda, decide who needs to be there, and run that week's activities. In addition, each of the clouds will have a coordinator who should decide which people supplying ancillary data should attend for at least the focus day on that cloud.


Here are the Coordinators:


Week 1:                        Lee (Clouds) and Ewine (IRS)

Clouds:                         Lee (Lupus), Paul (Serpens), Alicia (Cham)


Week 2:                        Lori (Clouds) and Geoff (IRS)

Clouds:                         Debbie (Oph), Karl (Perseus), Debbie (Taurus)

Cross-cutting:               Extinction in clouds/cores (Nicholas, Tracy)


Week 3:                        Phil (Cores) and Debbie (Stars)

Agenda for Stars: last two days of the meeting


03/23 received from Debbie


I presume that the last two days of the Leiden meeting will be devoted to WTTS. The people who should attend are myself, Karl, Dave, Lucas, Tim, Zahed (if possible),Jean-Charles, and Anneila. All others are welcome, of course It would be great to have an IRAC expert also. Here is an idea of what the agenda might cover. Of course, I would prefer to minimize the presentation part in favor of actually working toward finished papers. Since this comes so late, I presume that we will largely discuss our progress made during the Leiden meeting. I haven't discussed this agenda yet with the WTTS team, so the names are placeholders.

o Wrap-up and review action items and future schedule.


Our main onus is to show that all these negative detections are actually likely to be young stars associated with the clouds. I have already met with some skepticism on this account.
