Constraint on Brans-Dicke theory from Intermediate/Extreme Mass Ratio
  Inspirals with self-force method
  Intermediate/Extreme mass ratio inspiral (IMRI/EMRI) system provides a good
tool to test the nature of gravity in strong field. We construct the self-force
and use the self-force method to generate accurate waveform templates for
IMRIS/EMRIs on quasi-elliptical orbits in Brans-Dicke theory. The extra
monopole and dipole emissions in Brans-Dicke theory accelerate the orbital
decay, so the observations of gravitational waves may place stronger constraint
on Brans-Dicke theory. With a two-year observations of gravitational waves
emitted from IMRIs/EMRIs with LISA, we can get the most stringent constraint on
the Brans-Dicke coupling parameter $\omega_0>10^5$.
