The firrst spectra for the RX J0440.9+4431 from 2m Terskol telescope
We present the rst results on the spectra of Be/X-ray binary RX J0440.9+4431 obtained with the 2m Ritchey-Chretein-Coude telescope with Cassegrain Multi Mode Spectrograph (CMMS) (with R = 14000) at Terskol observatory. The Hα line pro le indicates that the new episode of the V/R variability is occu...
