Scientific paper

A semimajor photocentric orbit axis of 0.052 + or - 0.007 arc is indicated by an analysis of 55 plates of Wolf 630, in close agreement with the 0.056 + or - 0.018 arcmin previously reported. A comparison of fractional mass and absolute visual magnitude values arrived at in this investigation with those of other M dwarfs of known mass, it appears that the A component is the more normal of the two, and that the B component is underluminous for its mass by two or three magnitudes.
