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.

Axial rotation in NGC 2287
Axial and rotational velocities of the members of the open cluster NGC2287 are measured. The average rotation of the cluster is compared withthe average rotation of field stars of the same types; it is found thatNGC 2287 rotates at a slower rate than field stars. This result isdiscussed in terms of the correlation among the rotation, binarity, andpeculiarity among members of open clusters.
