Stochastic background from inspiralling double neutron stars

Abstract

We review the contribution of extra galactic inspiralling double neutron stars, to the LISA astrophysical gravitational wave foreground. Using recent fits of the star formation rate, we show that sources beyond $z_{\ast }=0.005$ contribute to a truly continuous background, which may dominate the LISA instrumental noise in the range $3\simeq 10^{-4}$ - $1\times 10^{-2}$ Hz and overwhelm the galactic WD-WD confusion noise at frequencies larger than ${\nu }_o\simeq 2\times 10^{-3}$.
