We propose a new method to detect gravitational waves, based on spatial
coherence interferometry with stellar light, as opposed to the conventional
temporal coherence interferometry with laser sources. The proposed method
detects gravitational waves by using two coherent beams of light from a single
distant star measured at separate space-based detectors with a long baseline.
This method can be applied to either the amplitude or intensity interferometry.
This experiment allows for the search of gravitational waves in the lower
frequency range of $10^{-6}$ to $10^{-4}$ Hz. In this work, we present the
detection sensitivity of the proposed stellar interferometer by taking the
detector response and shot and acceleration noises into account. Furthermore,
the proposed experimental setup is capable of searching for primordial black
holes and studying the size of the target neutron star, which are also
discussed in the paper.
