OBSERVATIONAL RESULTS OF STELLAR SPECKLE INTERFEROMETRIC SPECTROSCOPY

Stellar speckle spectroscopy is a speckle interferometric method enabl ing us to separate point by point spectra on a stellar object with a d iffraction-limited spatial resolution of a telescope. We describe obse rvational results obtained with our system for speckle spectroscopy. D ata of two binary stars, of which separations are closer than seeing d isc, were taken and processed by cross-correlation method. In each obj ect, spectral images of two component stars around the H alpha line (6 56.3 nm) were spatially resolved with nearly diffraction-limited resol ution. The separated spectra of ADS940 reveal different spectral types of the component stars. These results demonstrate the ability of the speckle spectroscopic method.
