Determination of the mass of asteroid (16) Psyche and masses of other asteroids of the taxonomic class M by the dynamic method

We use the dynamical method of estimation of the mass of perturbing asteroid by its gravitation influence on test asteroids. The positional observations of test asteroids from Minor Planet Center database and Focus Product Release of Gaia cosmic telescope are employed. The calculation of coordinates of perturbing planets is based on the ephemeris DE440. The set of test asteroids is used for estimation of perturbing mass. This set was collected by error of the mass of the perturbing asteroid for each test object. The number of test asteroids was selected particularly for each estimated mass. For the mass of asteroid (16) Psyche a value equal to $(1.1868\pm0.0092) 10^{-11} M_{\odot}$ was obtained. The masses of sixteen asteroids with numbers 55, 69, 75, 77, 83, 92, 97, 110, 129, 135, 201, 325, 441, 498, 516, and 739, that are from the taxonomic class M were estimated also. The estimated masses more than twice exceed their errors.
