  Circumstellar dust disks have been observed around many nearby stars.
However, many stars are part of binary or multiple stellar systems. A natural
question arises regarding the presence and properties of such disks in systems
with more than one star. To address this, we consider a sample of 449 systems
(spectral types A-M) observed with the Herschel Space Observatory as part of
the DEBRIS program. We have examined the stellar multiplicity of this sample by
gathering information from the literature and performing an adaptive optics
imaging survey at Lick Observatory. Five new companions were revealed with our
program. In total, we identify 188 (42%) binary or multiple star systems. The
multiplicity of the sample is examined with regards to the detection of
circumstellar disks for stars of spectral types AFGK.
  In general, disks are less commonly detected around binaries than single
stars, though the disk frequency is comparable among A stars regardless of
multiplicity. However, this sample reveals the period distribution of
disk-bearing binaries is consistent with that of non-disk binaries and with
comparison field samples. We find that the properties of disks in binary
systems are not statistically different from those around single stars.
Although the frequency of disk-bearing FGK binaries may be lower than in single
star systems, the processes behind disk formation and the characteristics of
these disks are comparable among both populations.
