Stellar Disk in the Galactic Center: A Remnant of a Dense Accretion Disk?
Open accessAbstract
Observations of the Galactic center revealed a population of young massive stars within 0.4 pc from Sgr A*—the presumed location of a supermassive black hole. The origin of these stars is a puzzle as their formation in situ should be suppressed by the black hole's tidal field. We find that out of 13 stars whose three-dimensional velocities have been measured by Genzel et al., 10 lie in a thin disk. The half-opening angle of the disk is consistent with zero within the measurement errors and does not exceed 10°. We propose that a recent burst of star formation has occurred in a dense gaseous disk around Sgr A*. Such a disk is no longer present because, most likely, it has been accreted by the central black hole. The three-dimensional orbit of S2, the young star closest to Sgr A*, has been recently mapped out with high precision. It is inclined to the stellar disk by 75°. We find that the orbit should undergo Lense-Thirring precession with the period of ~(6/ a ) × 10 6 yr, where a < 1 is the dimensionless spin of the black hole. Therefore, it is possible that originally the S2 orbit lay in the disk plane. The Lense-Thirring precession can turn the S2 orbit by 75° if a > 0.2( t S2 /6 × 10 6 yr) -1 , where t S2 is the age of S2.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
