Abstract

Space-based gravitational-wave detectors consist of a triangle of three spacecraft, which makesit possible to detect polarization modes of gravitational waves due to the motion of the detectors in space. In this paper we explore the ability of Taiji to detect the polarization modes in the parameterized post-Einsteinian framework. Assuming massive black hole binaries with the total mass of M = 4 × 10M at redshift of z = 1, we find that Taiji can measure the dipole and quadruple emission (∆αDD and ∆αQQ) with the accuracy of up to ∼ 0.04%, the scalar transverse and longitudinal modes (∆αB and ∆αL) up to ∼ 0.01, and the vector modes (∆αV ) up to ∼ 0.0005.
