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.

The evolution of asymptotic giant branch stars in the Large Magellanic Cloud. II - Spectroscopy of a complete sample
Spectra of 113 asymptotic giant branch (AGB) star candidatesconstituting six magnitude-limited, area-complete samples in the outerregions of the northern LMC have been obtained. Luminosity functionsconstructed from these data are well represented by an underlyingintermediate-mass AGB population, the product of continuous starformation over the last 3-4 Gyr, supplemented in some areas by moremassive red giant and supergiant stars, with a typical age of about 10to the 8th yr. Most stars with Mbol between -5 and -5.5 show evidencefor dredge-up of s-process elements, as do a smaller proportion in therange Mbol between -4.5 and -5. Only 10 percent of the sample, however,are C stars, and these are concentrated toward the Bar of the LMC. Noevidence has been found for envelope burning in any of the stars in thesample.
