Abstract
The Orbit of Sirius.—This orbit is of peculiar interest from the conspicuous brightness of the primary, from the irregularity in the proper motion having led to a prediction of its duplicity, and from the subsequent verification by the discovery of the companion in 1862. It now presents one of the not very numerous cases in which a complete revolution has' been observed. The various determinations of the elements that have recently been published give an index of the degree of accuracy that is attainable. A new determination by Mr. C. P. Howard is given in Pop. Ast. (Aug.-Sept. 1922), and that by Mr. R. Jonckheere (Mon. Not. R.A.S., June 1918) is printed for comparison. Both were made by graphical methods, using every refinement possible:
