FEPS Science Plan

SEE ALSO: [ feps science telecons ]

This document summarizes plans and progress on science associated with FEPS. Please note that this should be a constantly evolving document if our project is in a healthy state of productivity. As it is hard for us to keep track of who is planning/doing what and in collaboration with whom, please help us keep this page current by sending any and all updates and corrections to: lah(at)astro.caltech.edu. See the FEPS publications policy for guidelines as to how the paper writing process should work.

Red backgound indicates ``hot" papers on which imminent noteworthy progress and submission is expected. These are the ones we are trying hard to push out the door ASAP. Please do your part to help. Yellow background indicates ``warm" papers on which there has been recent activity, but not necessarily a mature draft for team comment. We need to submit these in 2006. Other papers are likely products of 2007, and some of those to which little attention has been devoted to date, may fall off the table.

Leads and deputy leads: please send outlines, collaborators, and paper drafts as they become available.

    Cycle 2 proposal for 25 hours (39 targets) approved.
    Cycle 3 proposal for 14 hours (19 targets) approved: list
    some observations obtained with several better/new detections at 70 and 160um

    Other potential Spitzer Ideas:
  • additional gas spectroscopy
  • other members of our parent sample, tossed off Legacy for various reasons

  • Even More Sub-mm Dust: SEDs (CSO, Scuba, SMT, AST/RO) Carpenter/Meyer
    many observations obtained

    some proposed observations

    looking for collaborator to work on data

    Even More Sub-mm Dust: Spatially Resolving Disks (SMA, PdB, ATCA, APEX) Carpenter/Meyer (Cortes)
    some observations obtained

    some allocated observations

    many proposed observations

    two sources of interest which are being analyzed with priority
