Galactic double white dwarf (DWD) binaries are among the guaranteed sources for Laser Interferometer Space Antenna (LISA), an upcoming space-based gravitational wave (GW) detector. Most DWDs in LISA band far from merging and emit quasimonochromatic GWs. As these distributed throughout Milky Way, they experience different accelerations potential, therefore each DWD exhibits apparent GW frequency chirp due to differential acceleration between source LISA. We examine how influences parameter estimation sources; investigate observations could provide insight into distribution of matter Galaxy.
