Speckle Interferometry of Southern Double Stars. III. Measures from the Cesco Observatory, 1994-1996
Position angle and separation measures of 482 primarily southern binarystars are presented. These were obtained from speckle observations takenat the Carlos U. Cesco Observatory, El Leoncito, Argentina, using amultianode microchannel array detector during the period 1994 July to1996 July. When comparing our measures to the ephemeris predictions inthe case of objects with well-determined orbits, we find that ourmeasures have a precision of approximately 13 mas per observation inseparation and 0.75d/ρ in position angle, where ρ is theseparation in arcseconds. We briefly discuss the photometric propertiesof the data and highlight four southern binaries of particular interestthat emerge from the list presented.

Two-colour photometry for 9473 components of close Hipparcos double and multiple stars
Using observations obtained with the Tycho instrument of the ESAHipparcos satellite, a two-colour photometry is produced for componentsof more than 7 000 Hipparcos double and multiple stars with angularseparations 0.1 to 2.5 arcsec. We publish 9473 components of 5173systems with separations above 0.3 arcsec. The majority of them did nothave Tycho photometry in the Hipparcos catalogue. The magnitudes arederived in the Tycho B_T and V_T passbands, similar to the Johnsonpassbands. Photometrically resolved components of the binaries withstatistically significant trigonometric parallaxes can be put on an HRdiagram, the majority of them for the first time. Based on observationsmade with the ESA Hipparcos satellite.

ICCD speckle observations of binary stars. VIII - Measurements during 1989-1991 from the Cerro Tololo 4 M telescope
One-thousand eighty-eight observations of 947 binary star systems,observed by means of speckle interferometry with the 4 m telescope onCerro Tololo, are presented. These measurements, made during the period1989-1991, comprise the second installment of results stemming from theexpansion of our speckle program to the southern hemisphere.
