Description

Gravitational waves have proven to be an excellent tool for
understanding populations of binaries. For the upcoming LISA detector,
Binary White Dwarfs are one of the most promising sources. In this work,
we focus on modelling the Gravitational wave background from White Dwarf
Binaries in the LISA sensitivity range and building a model of their
population in the Milky Way.
The COMPAS binary synthesis program is used for population synthesis of
the White Dwarf Binaries. Various evolution prescriptions and initial
model parameters are used to study diverse population of White Dwarf
Binaries. We investigate the dependence of the background spectrum on
the assumptions on binary analysis. We discuss the possibility of
constraints on binary evolution that LISA gravitational wave
observations may yield
