| Summary: | 碩士 === 國立臺灣師範大學 === 地球科學系 === 97 === The binary image will be distorted by atmospheric turbulence, however the angular separation of a binary could be determined with speckle interferometry technology. The binary program with speckle interferometry at NTNU has been set up since 2002.
The commercial CCD, DMK 31AF03 CCD, is suitable for the binary program with the method of speckle interferometry. Because C-14 is the telescope with a moving primary mirror, it is not suitable for speckle observations.
There are 22 binaries chosen for our 2009 program, and the parameters of 13 binaries are determined. Their angular separations are between 0.61 ~ 8 arcsecs. The brightnesses of the primary stars fall between 1.93~5.64 mag.
