Radial Velocities of the Components of the Trapezium Type Multiple Systems Not Available
Radial Velocities of the Components of Trapezium-Type Multiple Stellar Systems - Part Two Not Available
Radial velocities of the components of multiple star systems of Trapezium type. I. Not Available
Photoelectric UBV-photometry of triple-star components Photoelectric UBV photometry was performed on components of 30 brightand nearby triple stars to identify physically linked triple systems andto determine their distances and dynamic evolution. An analysis of 60catalogs showed only 10 triple systems. For every component, E(B-V) andE(U-B) color excesses are determined and photometric parallaxes arecalculated using available spectral types.
The radial velocities of triple-star components The paper presents 60 radial velocity measurements for 38 components of22 triple stars. Information is provided on the radial velocities of thetriple-star systems ADS 48,9716,9909 + + 9910, 10058, 11853 and of atriple star with alpha (1950) = 18 h 45 min, and delta (1950) = + 28 deg22 arcmin.
The Equatorial Coordinates of Components of Triple Stars from the Astrometric Satellite HIPPARCOS Input Catalogue - Part Two - the Results of Statistical Study of Data from Aitken's Catalogue of Double Stars / ADS Not Available
Visual multiples. VIII - 1000 MK types A total of 1000 new classifications are given for stars brighter than B= 8.0 mag in the Aitken double star catalog. The classificationssupplement 865 classifications obtained in 1981 and 1984. Among thenewly discovered stars are 12 new Ap stars, eight Lambda Bootis stars,one Ba II star, and 60 Am stars. A detailed list of the newclassifications is given.
