Abstract
Most all-sky searches for continuous gravitational waves assume the source to
be isolated. In this paper, we allow for an unknown companion object in a
long-period orbit and opportunistically use previous results from an all-sky
search for isolated sources to constrain the continuous gravitational wave
amplitude over a large and unexplored range of binary orbital parameters
without explicitly performing a dedicated search for binary systems. The
resulting limits are significantly more constraining than any existing upper
limit for unknown binary systems, albeit the latter apply to different orbital
parameter ranges.
