We present the results of a high-resolution study with the Submillimeter Array(SMA)toward the massive star-forming complex G20.08–0.14N.With the SMA data,we ha
We have carried out observations of 12 CO J=2-1 and 12 CO J=3-2 toward the high-mass protostellar candidate IRAS 20188+3928.Compared with previous observations,
At present, optical autonomous navigation has become a key technologyin deep space exploration programs. Recent studies focus on the problem of orbit de-termina
We investigate the effects of a global magnetic field on the dynamics of an ensemble of clumps within a magnetized advection-dominated accretion flow by ignorin
