- Some have asked what the
ALMA Band requirements actually are, so from the adopted system
technical requirements here is a table:
Science Corner: Sebastian Wolf writes: Our most
recent feasibility study concerning future observations of young
circumstellar disks with embedded giant planets with the Atacama Large
Millimeter Array makes the prediction of possible detections not only
of the gap created by giant planets, but also of the local hot and
dense circumplanetary environment, indicating the location of the
planet in the gap. See:
Fig. 2.— Simulation of ALMA observations of disk with an
embedded planet of 1Mjup
(left column) / 5Mjup (right column) around a 0.5M⊙ / 2.5M⊙ star
(orbital radius: 5AU).
The assumed distance is 50 pc (top row) / 100 pc (bottom row). The disk
to Mdisk = 1.0 × 10−2M⊙. Only structures above the 2sigma -level
are shown. The size of the
combined beam is symbolized in the lower left edge of each image. Note
shape of the spiral wave near the planet and the slightly shadowed
region behind the planet
in the upper images.

for background information on some discussed items.
Al Wootten has also created an ANASAC wiki page at NRAO for this
collaborative effort. You can find the link as https://wikio.nrao.edu/bin/view/ALMA/AlmaNorthAmericanScienceAdvisoryCommittee.
You will find my earlier e-mail and the web link to the sample survey
questions if you click on "NaascSurvey" wiki word on the front page.
you are just browsing, you need not do much else. If you want to
contribute material to these wiki pages, you can visit https://wikio.nrao.edu/bin/view/TWiki/WelcomeGuest

Several points regarding use of the wiki:
Any registered user may put text on a wiki page or construct a new one.
Please let Wootten know if you have questions about this process.
When you edit a page you lock it. ¨
A file lock will time out and release after one hour of inactivity.
A file lock can be overridden (please do not do this). ¨
The wiki has lots of plugins (like one which allows for an interactive
group action item list) which will be installed over the coming weeks.
