Planet-Disk Interaction and Orbital Evolution (2012, background): “5, the existence of giant planets in 2:1 mean motion resonances, such as the GJ 876 (Marcy et al., 2001) and Kepler-9 (Holman et al., 2010) systems, suggests that the differential migration in these systems was relatively slow when the resonances were established.”
A ~7.5 M⊕ Planet Orbiting the Nearby Star, GJ 876 (2005, methodology): “Marcy et al. (2001) noted that although a model with two planets on unperturbed Keplerian orbits produces a very sig- nificantly improved fit to the radial velocity data by dramatically reducing both the ( 2 ) 1/2 and the rms of the fit,10 these two statistics were still relatively large.”

THE CALIFORNIA PLANET SURVEY. I. FOUR NEW GIANT EXOPLANETS (2010, background): “We note with interest that Gl 179 is an almost identical twin to Gl 876, an M dwarf known to host two Jovian planets locked in resonant orbits and a super-Earth in a P =1.9 d orbit (Marcy et al. 2001; Rivera et al. 2005).”

(2002, background): “…& Quinn 2001; Laughlin & Adams 1999; Quinlan 1992; Rivera & Lissauer 2000; Stepinski et al. 2000, for example,) point to a high frequency of marginally stable systems around stars as well as the discovery of the marginally stable planetary systems around GJ876 and HD 82943 (Marcy et al. 2001).”
Improving the Efficiency of Markov Chain Monte Carlo for Analyzing the Orbits of Extrasolar Planets (2005, background): “GJ 876 The multiple-planet system around the M dwarf GJ 876 is particularly interesting, as there are two massive planets in a 2:1 mean motion resonance (Marcy et al. 2001, Benedict et al. 2002).”
