Description |
We carried out high-speed low-resolution spectroscopy of two stars, 61 Cyg A and B with small telescopes. They are known as chromospherically active stars of the K5V (A) and K7V (B) spectral types. These two stars are supposed to have high-powered chromospheres. Spectroscopic monitoring of both stars showed variations of intensity in the Balmer lines and the Mg b triplets at time intervals ranging from seconds to several minutes. From the spectrum data one can find that relative variations in the Hα, Hβ lines and the Mg b triplets are about 1% and the relative power of chromospheric activity about 2 · 10⁻⁴.
