Query: Jets from Accreting White Dwarfs   Collimated outflows from accreting white dwarfs have an important role to
play in the study of astrophysical jets. Observationally, collimated outflows
are associated with systems in which material is accreted though a disk.
Theoretically, accretion disks provide the foundation for many jet models.
Perhaps the best-understood of all accretion disks are those in cataclysmic
variable stars (CVs). Since the disks in other accreting white-dwarf (WD)
binaries are probably similar to CV disks (at least to the extent that one does
not expect complications such as, for example, advection-dominated flows), with
WD accretors one has the advantage of a relatively good grasp of the region
from which the outflows are likely to originate. We briefly compare the
properties of the three main classes of WD accretors, two of which have members
that produce jets, and review the cases of three specific jet-producing WD
systems.
