Visual binaries: cross-matching and compiling of a comprehensive list

Kovaleva, D. A.; Malkov, O. Yu.; Isaeva, A. A.

Visual binary stars make up the largest set among observed types of binaries (currently more than 110 000 systems are known containing more than 230 000 components). However, statistical analysis of this sample is a complicated task because a number of catalogues of visual binaries contain various data for evidently overlapping sets of objects. To…

A new estimate of the Local Standard of Rest from data on young objects

Bobylev, V. V.; Bajkova, A. T.

To estimate the peculiar velocity of the Sun with respect to the Local Standard of Rest (LSR), we use young objects in the Solar neighborhood with distance measurement errors within 10%--15%. These objects include the nearest Hipparcos O--B2.5 type stars, masers with VLBI trigonometric parallaxes, and two samples consisting of the youngest and mid…
