The AOS TB  Shell Arises The AOS TB Shell Arises: 15 Feb


  • Science Requirements -- Yet another Version of the revised document is located in the Science area.
  • AIVCSV face-to-face/SRR followup -- discussion centers on late April Garching or Santiago.
  • EPO items:
    • Talk on ALMA Ops, NAASC in Victoria 17 August at Submillimeter Observing Techniques school. Any volunteers?
    • Talk on Great Observatories, 22-24 May in Pasadena. Volunteers?
  • ITU; Spectral line items.
  • ICDs:
    • Sci-Comp
    • Sci-Site
  • Calibration: ACA discussion held last Monday with Japan
  • DRSP: ASAC will ask for this to be expanded to include B4, B5, B8, B10(?) and ACA.
  • ASAC Charge. Board considering a charge to run through scheduling DRSP against site char results.
  • Operations redux. Plan quasi-approved. Budget has not been approved. This was the culmination of a lot of work. Situation is pretty much the same today. Some changes are needed--we have more flexibility, more mandate to minimize cost. The existing plan is OSF-centric. Technical and administrative items occur there. This is reflected in the buildings. They have been modified somewhat by cost. We still have the floor space but we might reconsider whether things could be done better in Santiago, at the Executives or by contractors. Building in Santiago is in baseline budget for Vitacura. The estimate is parametric at the moment. If a coherent case can be made for doing something more cost-effectively in Santiago, resources can be diverted to Santiago. IPTs must argue their way back into the OSF for that to occur. Antenna obviously an OSF task but perhaps not nutator. Cryostat needs to be done at OSF but perhaps not other r x items. Send Tiger Team from Santiago when needed. Of perhaps from CV or RAL. If Executives, then more spares probably needed. There are many options. The OSF building is going on but outfitting will reflect these decisions. Same for Santiago building. Timeline for turning around this discussion is probably a few months.

Science Corner:

Talk at UVa yesterday by Ed Thommes. Young planets interact with their parent gas disks through tidal torques. An imbalance between inner and outer torques causes bodies of mass $\ga 0.1$ Earth masses to lose angular momentum and migrate inward rapidly relative to the disk; this is known as ``Type I'' migration. But planets are observed. He proposed a Balbus-Hawley instability occurs in the midplane of the disk where stellar ionization is unimportant and cosmic ray ionization is also unimportant owing to column depth, a 'dead zone'. In this case, material accumulates in this zone and can modulate the migration of giant planets further out while nurturing the formation of terrestrial planets and circularizing their orbits. This has observable consequences for ALMA. Protoplanets that grow to gas giant mass, O($10^2) M_\oplus$, open a gap in the disk and are subsequently constrained to migrate more slowly, locked into the disk's viscous evolution in what is called "Type II" migration. The contrast between the gap formed by the giant planet and the higher column density in the inner region should make observation by ALMA achievable.
