# Parameter estimation accuracies of Galactic binaries with eLISA

## TL;DR

This paper evaluates how accurately eLISA-like gravitational wave detectors can estimate parameters of nearly monochromatic signals from galactic binaries, informing their scientific potential and mission design choices.

## Contribution

It provides a comparative analysis of parameter estimation accuracies for different eLISA mission configurations using Fisher matrix methods.

## Key findings

- eLISA can observe millions of galactic binary signals
- Parameter estimation accuracy varies with mission design
- Thousands of sources can have their parameters precisely estimated

## Abstract

We study parameter estimation accuracy of nearly monochromatic sources of gravitational waves with the future eLISA-like detectors. eLISA will be capable of observing millions of such signals generated by orbiting pairs of compact binaries consisting of white dwarf, neutron star or black hole and to resolve and estimate parameters of several thousands of them providing crucial information regarding their orbital dynamics, formation rates and evolutionary paths. Using the Fisher matrix analysis we compare accuracies of the estimated parameters for different mission designs defined by the GOAT advisory team established to asses the scientific capabilities and the technological issues of the eLISA-like missions.
