Abstract

A set of distance and velocity data previously obtained and analyzed is rediscussed to determine the surface mass density of the Galactic disk. These data reliably determine the integral surface mass density of all (disk + halo) Galactic components within 1.1 kpc from the Galactic plane near the sun to be 71 + or 6 solar masses/sq pc, independent of the disk/halo ratio. Determination of the fraction of this total mass which is distributed in the Galactic disk and the fraction which is associated with an extended halo remains highly model-dependent. The best available estimate of the relative contributions of disk mass and halo mass to the local integral surface density, obtained from modeling of the Galactic rotation curve, yields a surface mass density of 48 + or - 9 solar masses/sq pc for mass associated with the Galactic disk near the sun. The corresponding mass of identified disk matter is 48 + or - 8 solar masses/sq pc.

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.
