The mass–luminosity relation for late-type stars has long been a critical tool for estimating
stellar masses. However, there is growing need for both a higher-precision relation and a …

We report on the results of speckle observations at the 4.1 m SOAR telescope in 2010 and
2011. A total of 639 objects were observed. We give 562 measurements of 418 resolved …

In this work, we present a detailed analysis of the individual components of the visual binary
system HIP 102029 (RA= 20: 40: 35.32, Dec.=+ 15: 38: 35.63). The system was discovered …

Results are presented for 607 speckle interferometric observations of double stars, as well
as 222 measures of single stars or unresolved pairs. All data were obtained in 2006 and …

Joint analysis of radial velocities and position measurements of five hierarchical stellar
systems is undertaken to determine elements of their inner and outer orbits and, whenever …

The results of 3047 speckle interferometric observations of double stars, made with the 26
inch (66 cm) refractor of the US Naval Observatory, are presented. Each speckle …

The results of 1657 speckle interferometric observations of double stars, made with the 26
inch (66 cm) refractor of the US Naval Observatory, are presented. Each speckle …

Long-term monitoring at the 6 m telescope of the Special Astrophysical Observatory of the
Russian Academy of Sciences made it possible to improve the orbits of 15 objects (HIP 689 …

The results of 1424 speckle interferometric observations of double stars, made with the 26
inch (66 cm) refractor of the US Naval Observatory, are presented. Each speckle …

Abstract The US Naval Observatory has mined over 140 astrometric catalogs, including the
Astrographic Catalogue and the Two Micron All Sky Survey, for measures of double stars …
