Proper motion derivatives of binaries
Listed in IVOA Registry (Virtual Observatory)
Useful constraints on the orbits and mass ratios of astrometric binaries in the Hipparcos catalog are derived from the measured proper motion differences of Hipparcos and Tycho-2 ({Delta}{mu}), accelerations of proper motions (d{mu}/dt) and second derivatives of proper motions (d^2^{mu}/dt^2^).
Description
It is shown how, in some cases, statistical bounds can be estimated for the masses of the secondary components. Two catalogs of astrometric binaries are generated, one of binaries with significant proper motion differences and the other of binaries with significant accelerations of their proper motions.
