Binaries for LISA
Binaries sufficiently compact to be observed with LISA consist of small stars, with both chosen from the following list: low-mass main sequence stars, white dwarfs, neutron stars, black holes or helium-burning cores of high-mass stars. The numbers of various types of binaries can be derived from observations, provided that observational selection effects are taken into account. They can also be...
متن کاملParameter estimation for Galactic binaries by LISA
We calculate how accurately parameters of the short-period binaries (10 Hz . f . 10 Hz) will be determined from the gravitational waves by LISA. In our analysis the chirp signal ḟ is newly included as a fitting parameters and dependence on observational period or wave frequency is studied in detail. Implications for gravitational wave astronomy are also discussed quantitatively. Subject heading...
متن کاملDetecting Eccentric Globular Cluster Binaries with LISA
The energy carried in the gravitational wave signal from an eccentric binary is spread across several harmonics of the orbital frequency. The inclusion of the harmonics in the analysis of the gravitational wave signal increases the signal-to-noise ratio of the detected signal for binaries whose fundamental frequency is below the galactic confusion-limited noise cut-off. This can allow for an im...
متن کاملTomographic approach to resolving the distribution of LISA Galactic binaries
The space based gravitational wave detector LISA is expected to observe a large population of Galactic white dwarf binaries whose collective signal is likely to dominate instrumental noise at observational frequencies in the range 10−4 to 10−3 Hz. The motion of LISA modulates the signal of each binary in both frequency and amplitude, the exact modulation depending on the source direction and fr...
متن کاملGolden Binaries for LISA: Robust Probes of Strong-Field Gravity
The space interferometer LISA will detect the gravitational wave (GW) signal from the inspiral, plunge and ringdown phases of massive black hole binary mergers at cosmological distances. From the inspiral waves, we will be able to measure the masses of the binaries’ members; from the ringdown waves, we will be able to measure the mass of the final merged remnant. A subset of detected events all...
