摘要：

We analyze the sensitivities of a geostationary gravitational wave interferometer mission operating in the sub-Hertz band. Because of its smaller armlength, in the lower part of its accessible frequency band (10(-4) - 2 x 10(-2) Hz) our proposed Earth-orbiting detector will be less sensitive, by a factor of about seventy, than the Laser Interferometer Space Antenna (LISA) mission. In the higher part of its band instead (2 x 10(-2) - 10 Hz), our proposed interferometer will have the capability of observing super-massive black holes (SMBHs) with masses smaller than similar to 10(6) M-circle dot. With good event rates for these systems, a geostationary interferometer will be able to accurately probe the astrophysical scenarios that account for their formation. (c) 2013 Elsevier B.V.
