Recent measurements of the velocities of stars near the centre of the Milky Way have provided the strongest evidence for the presence of a supermassive black hole in a galaxy, but the observational uncertainties poorly constrain many of the black hole's properties. Determining the accelerations of stars in their orbits around the centre provides much more precise information about the position and mass of the black hole. Here we report measurements of the accelerations of three stars located ∼0… 
Star close to the massive black hole at center of the Milky Way
Recent measurements of stellar velocities ([5], [7]) and variable X-ray emission [3] near the center of the Milky Way have already provided the strongest case for the presence of a super-massive
Probing the properties of the Milky Way's central supermassive black hole with stellar orbits
Abstract We report new precision measurements of the properties of our Galaxy's supermassive black hole. Based on astrometric (1995-2007) and radial velocity (2000-2007) measurements from the W. M.
The Galactic Center stellar cluster: The central arcsecond
With 10 years of high-resolution imaging data now available on the stellar cluster in the Galactic Center, we analyze the dynamics of the stars at projected distances ≤1.2″ from the central black
Closest Star Seen Orbiting the Supermassive Black Hole at the Centre of the Milky Way a
Measurements of stellar velocities 1−6 and variable X-ray emission 7 near the centre of the Milky Way have provided the strongest evidence so far that the dark mass concentrations seen in many
A star in a 15.2-year orbit around the supermassive black hole at the centre of the Milky Way
Ten years of high-resolution astrometric imaging allow us to trace two-thirds of the orbit of the star currently closest to the compact radio source (and massive black-hole candidate) Sagittarius A* and show that the star is on a bound, highly elliptical keplerian orbit around Sgr A*.
Periastron shifts of stellar orbits near the Galactic Center
The presence of a $2.9\pm0.4$ million solar mass object in the central stellar cluster of the Milky Way has recently been demonstrated via measurements of the stellar proper motions and radial
Stellar Orbits at the Center of the Milky Way
During the past ten years, measurements of stellar proper motion, and radial velocities (Eckart et al. 2002, Genzel et al. 2000, Ghez et al. 2000) as well as variable X-ray emission (Baganoff et al.
The Motion of Stars near the Galactic Center: A Comparison of the Black Hole and Fermion Ball Scenarios
After a discussion of the properties of degenerate fermion balls, we analyze the orbits of the stars S0-1 and S0-2, which have the smallest projected distances to Sgr A*, in the supermassive black
The nuclear star cluster of the Milky Way: proper motions and mass
Context. Nuclear star clusters (NSCs) are located at the photometric and dynamical centers of the majority of galaxies. They are among the densest star clusters in the Universe. The NSC in the Milky
Gravitational Waves from Stars Orbiting the Sagittarius A* Black Hole
One of the main astrophysical processes leading to strong emission of gravitational waves to be detected by the future space-borne interferometer Laser Interferometer Space Antenna (LISA) is the


The case against a massive black hole at the Galactic Centre
MANY of the compact near-infrared sources observed in the central parsec of our Galaxy have been shown to be very massive, luminous blue stars with strong helium lines and fast winds, perhaps similar
Proper Motion of the Compact, Nonthermal Radio Source in the Galactic Center, Sagittarius A*
Proper motions and radial velocities of luminous infrared stars in the Galactic center have provided strong evidence for a dark mass of 2.5 × 106 M☉ in the central 0.05 pc of the Galaxy. The leading
Stellar dynamics in the Galactic centre: Proper motions and anisotropy
We report a new analysis of the stellar dynamics in the Galactic Centre, based on improved sky and line-of-sight velocities for more than 100 stars in the central few arcseconds from the black hole
Over a 2 year period we have conducted a di†raction-limited imaging study at 2.2 km of the inner 6A ] 6A of the central stellar cluster of the Galaxy using the W. M. Keck 10 m telescope. The K-band
Stellar proper motions in the central 0.1 PC of the galaxy
We report the first results of a programme to measure proper motions of stars in the innermost core of the Galaxy. From high-resolution near-infrared imaging over the last four years we have

We present a new geometrical method for measuring the distance to the Galactic center (R0) by solving for the Keplerian orbit of individual stars bound to the black hole associated with Sgr A* from
The distance to the center of the Galaxy
For nearly a century astronomers have expended considerable effort to determine the size of the Milky Way. This effort is worthwhile because any change in the value of the distance from the Sun to
