Sebastian Wolf writes: The new
simulation was done for an observing wavelength of * 870mu *,
instead of 330mu.
These simulations show that the locally heated region around
the (proto)planet is not visible anymore, even if the system
is in a distance of only 50pc. The assumed system
temperature is 220K (compared to 1200K at 900GHz - based on ALMA Memo
All other parameters (phase noise, pointing error/model, etc.)
are the same as in Wolf & D'Angelo (2005;
The main reason for the negative result is the fact that the
hot region around the planet has a small diameter only.
Increasing the beam size, this signal is smoothed with the almost
zero signal of the low-density gap and cannot be distinuished
anymore from the bright region of the disk outside the gap.
That's at least my understanding of the situation (which I found
to be true in all other simulations I performed).
Fig. 2. Simulation of ALMA observations of disk with an
embedded planet of 1Mjup around a 0.5M⊙ star
(orbital radius: 5AU).
The assumed distance is 50 pc or 100 pc as labeled. The disk
mass is set to that of the Butterfly Star in Taurus. Note
shape of the spiral wave near the planet and the slightly shadowed
region behind the planet
in the upper images.
