The Galactic Low Mass X-ray Binary GX339-4 was one of the earliest proposed black hole candidates, yet even its most fundamental binary parameters have eluded...
Dynamical evidence for a black hole in the x-ray transient QZ VUL (=GS 2000+25)
We report the spectroscopic detection of the secondary star in the x-ray transient QZ Vul (=GS 2000+25). Cross-correlation of individual spectra against K-type...
Dynamical evolution of a bulge in an N-body model of the Milky Way
The detailed dynamical structure of the bulge in the Milky Way is currently under debate. Although kinematics of the bulge stars can be well reproduced by a...
Dynamical masses for the nearest brown dwarf binary: ɛ Indi Ba, Bb
We present preliminary astrometric results for the closest known brown dwarf binary to the Sun: V Indi Ba, Bb at a distance of 3.626 pc. With ongoing monitoring...
Dynamical masses for the nearest brown dwarf binary: ɛ Indi Ba,b
Binary brown dwarfs are important because their dynamical masses can be determined in a model-independent way. If a main sequence star is also involved, the age...
Dynamical Models of SAURON and CALIFA Galaxies: 1D and 2D Rotational Curves
The mass of a galaxy is the most important parameter to understand its structure and evolution. The total mass we can infer by constructing dynamical models...
We present a general study of the dynamical properties of Anisotropic Bianchi Universes in the context of Einstein General Relativity. Integrability results...
