Gravitational wave spectral synthesis

Abstract We study the LISA sources that arise from isolated binary evolution, and how these depend on age metallicity, using model stellar populations bpass. as single-aged which are analogous to star clusters. calculate combined GW spectrum of all binaries within clusters, including types compact well those with living stars. These results allow us evaluate detectability clusters LISA. find at late times dominant WD–WD by factors 50–200, but between 108 109 years we a significant population NS–WD BH–WD (2–40 per 106 M⊙), is related treatment mass transfer common envelope events in bpass, wherein relatively likely be stable. Metallicity also has an effect relative dominance different binaries. Using information about known will aid identification sky locations where one could expect sources.
