4 Nov 2001 | | Journal: | Astron.Lett. 28 (2002) 143-149 | | Subject: | astro-ph gr-qc | | Affiliation: | 1,2), M.E.Prokhorov ( Sternberg Astronomical Insitute, Moscow MPA fuer Astrophysik, Garching | | Abstract: | Maximum gravitational wave emission from binary stars in eccentric orbits occurs near the periastron passage. We show that for a stationary distribution of binary neutron stars in the Galaxy, several high-eccentricity systems with orbital periods in the range from tens of minutes to several days should exist that emit broad gravitational-wave pulses in the frequency range 1-100 mHz. The space interferometer LISA could register the pulsed signal from these system at a signal-to-noise ratio level $S/N>5sqrt{5}$ in the frequency range $sim 10^{-3}-10^{-1}$ Hz during one-year observational time. Some detection algorithms for such a signal are discussed. | | Source: | arXiv, astro-ph/0111066 | | Services: | Forum | Review | PDF | Favorites | |
