Beginning of ReadMe : J/other/AstBu/63.278 Metal-poor stars speckle interferometry (Rastegaev+, 2008) ================================================================================ Speckle interferometry of metal-poor stars in the solar neighborhood. II. Rastegaev D.A., Balega Yu.Yu., Maksimov A.F., Malogolovets E.V., Dyachenko V.V. <Astrophys. Bull., 63, 278-289 (2008)> =2008AstBu..63..278R (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Stars, nearby ; Stars, double and multiple Abstract: The results of speckle interferometric observations of 115 metal-poor stars ([m/H]<-1) within 250pc from the Sun and with proper motions mu> 0.2"/yr, made with the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences, are reported. Close companions with separations ranging from 0.034" to 1" were observed for 12 objects - G76-21, G59-1, G63-46, G135-16, G168-42, G141-47, G142-44, G190-10, G28-43, G217-8, G130-7, and G89-14 - eight of them are astrometrically resolved for the first time. The newly resolved systems include one triple star - G190-10. If combined with spectroscopic and visual data, our results imply a single:binary:triple:quadruple star ratio of 147:64:9:1 for a sample of 221 primary components of halo and thick-disk stars.
