Scientific paper

A number of possible sightings of a third star in the Sirius system were reported in the 1920s. Astrometric observations have recently ruled out the presence of a very close companion to either Sirius A or B; however, a third star could exist at large distances. The stability of possible orbits of such a third star was investigated and it was found that the shortest stable orbital period is 275 years
