Radial velocities of 35495 Hipparcos stars in a common system

Gontcharov, G. A.

The Pulkovo Compilation of Radial Velocities (PCRV) catalogue has been produced to study stellar kinematics in the local spiral arm. The PCRV contains the mean weighted absolute radial velocities of 35495 Hipparcos stars of various spectral types and luminosity classes over the whole celestial sphere mainly within the radius of 500pc from the Sun.…

The rotational vector of the Local Stellar System

Tsvetkov, A. S.

It is shown that the rotational vector of nearby stars derived from the proper motions of the Hipparcos catalogue is not perpendicular to the Galactic plane. We found that the rotation of stars nearer than 150 pc can be considered as the superposition of the Galactic rotation and the Local Stellar System rotation. The kinematics of stars which are…

Search for the periodicity in brightness and radial velocity variations of the runaway star HD 218915

Barannikov, A. A.

An analysis of the variations in the brightness and radial velocity of the high-velocity (runaway) star HD 218915 based on the author's ground-based Crimean observations and from Hipparcos data is presented. The analysis leads to the conclusion that there is a periodic component in the brightness and radial velocity variations of HD 218915. The pe…

Autocorrelation and Fourier analysis of the Crimean and Hipparcos photometry of the runaway star HD 192281

Barannikov, A. A.

New B sbnd V sbnd R photoelectric photometry of the runaway star HD 192281 combined with Hipparcos observations of this star show a periodic brightness variation with a period of 67.385 days.
