The Discovery and Observed Properties of QSOs at Large Redshifts — An Updateat least so far, had to rely on the detection and study of high redshift QSOs. This review covers work, principally on quasi-stellar objects with large redshifts, that has come to my attention in the interval May 1978 to February 1981. I have assumed, except where otherwise noted, that redshift is a

The Roche Dimensions of Rotating Gaseous Disks in Close Binary Systemslow with the aid of the Roche coordinates. Assuming, as a sufficient approximation, that the rotating gas flows around one component in a close binary system move along zero- velocity curves in the orbital plane, a certain simple relation can be deduced between the flow velocity and the outward dens

Close Binary Systems of Short Periodces. The organization of the presentation depends on a light curve descriptor which takes the values EA1, EA2, EA3, EB, EW and E 11. Within these groups the distribution in the spectral type (s): period (P) plane is examined. An additional distribution of this kind is presented for 311 EA2 candidate

Techniques for Simulating Galactic CollisionsThe much larger regions separating the galaxies must be treated in the same detail with current fast Fourier transform based potential solvers. This paper describes a mesh segmentation technique which permits us to solve very large potential problems and to concentrate our effort on the regions wher
