The speckle interferometric multiplicity of T Tauri type stars in the Taurus-Auriga star-forming region

We present the results of a multiplicity study of T Tau-type stars in the Taurus-Auriga association. The observational data were obtained by speckle interferometry at the 6-meter telescope of the SAO RAS in 2020 and 2024. For the resolved stars, the positional parameters of the components, as well as the magnitude differences, were determined using the reference-independent power spectrum modeling method. Among the sample containing 58 bright stars ($m_{V} \leq 10$ mag), 12 binary, 5 triple and one quadruple speckle-interferometric systems were detected.
