Abstract:
Post-AGB binaries are surrounded by massive disks of gas and dust that
are similar to protoplanetary disks surrounding young stars.
We assembled a catalog of all known Galactic post-AGB binaries with
disks. We explore correlations between the different observables with
the aim to learn more about potential disk-binary interactions.
We compiled spectral energy distributions of 85 Galactic post-AGB
binary systems. We built-up a color-color diagram to differentiate
between the different disk morphologies traced by the characteristics
of the infrared excess. We categorised different disk types and looked
for correlations with other observational characteristics of these
systems.
8 to 12% of our targets are surrounded by transition disks, i.e. disks
having no or low near-infrared excesses. We find a strong link between
these transition disks and the depletion of refractory elements seen
on the surface of the post-AGB star. We interpret this correlation as
evidence for the presence of a mechanism that stimulates the dust and
gas separation within the disk and which also produces the transition
disk structure. We propose that such a mechanism can be a giant planet
carving a hole in the disk which traps the dust in the outer disk
parts. We propose two disk evolutionary scenarios, depending on the
presence of such a giant planet in the disk.
We advocate that giant planets can successfully explain the
correlation between the transition disks and the depletion of
refractory materials observed in post-AGB binaries. If the planetary
scenario is confirmed, disks around post-AGB binaries could be a
unique laboratory to test planet-disk interactions and their influence
on the late evolution of binary stars. Whether the planets are first
or second generation also remains to be studied. We argue that these
disks are the perfect place to study planet formation scenarios in an
unprecedented parameter space.
Description:
The table lists all the Galacti post-AGB binaries we have identified.
We included the infrared colors we have computed from existing
measurements. We also indicate the category of the objects together
with information on the orbit and, depletion.

Note (1): Categories as follows:
Cat. 0 = H-Ks>1.15, W1-W3<4.5. This region of the color-color diagram is
populated by several observed targets and is on top of the full
disk models.
Cat. 1 = 0.3< H-Ks<1.15, W1-W3<4.5, It encompasses the area occupied by models
of full disks
Cat. 2 = 0.3< H-Ks<1.15, W1-W3>4.5, It includes all the models that have high
mid-infrared colors and that are populated by variations of models
of AC Her, namely, of disks with large cavities
Cat. 3 = H-Ks<0.3, 2.3<W1-W3<4.5, It covers the targets with low near-infrared
colors and medium mid-infrared colors. This area is populated by
transition disk models but include can also full disk models
without the ad-hoc extended component.
Cat. 4 = H-Ks<0.3, W1-W3<2.3, It includes targets with low near-infrared and
mid-infrared excesses. It is occupied by models of transition disks.
