The influence of star formation history on the gravitational wave signal
  from close double degenerates in the thin disc
  The expected gravitational wave (GW) signal due to double degenerates (DDs)
in the thin Galactic disc is calculated using a Monte Carlo simulation. The
number of young close DDs that will contribute observable discrete signals in
the frequency range $1.58 - 15.8$ mHz is estimated by comparison with the
sensitivity of proposed GW observatories. The present-day DD population is
examined as a function of Galactic star-formation history alone. It is shown
that the frequency distribution, in particular, is a sensitive function of the
Galactic star formation history and could be used to measure the time since the
last major star-formation epoch.
