M. Schoeller et al., DIFFRACTION-LIMITED SPECKLE MASKING INTERFEROMETRY OF BINARY STARS WITH THE SAO 6-M TELESCOPE, Astronomy letters, 24(3), 1998, pp. 283-287
Optical speckle masking observations of 32 binary and multiple stars w
ith the SAO 6-m telescope are presented. The resolution of the reconst
ructed diffraction-limited images is 23 mas at 656 nm. Accurate magnit
ude differences were first determined for most binaries. The results f
or individual systems are compared with the available orbits and with
published photometric data. A new close visual component was discovere
d in the multiple system ADS 784.
