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_*=0.005 contribute to a truly continuous background, which may dominate the LISA instrumental noise in the range 3\ensuremath≃10^\ensuremath-4--1\ifmmode×\else\texttimes\fi10^\ensuremath-2 Hz and overwhelm the galactic WD-WD confusion noise at frequencies larger than \ensuremathν_o\ensuremath≃2\ifmmode×\else\texttimes\fi10^\ensuremath-3.
