Scientific paper

The splitting of the Hα line and the emission in its core were
discovered in the spectrum of the RRc-type pulsating variable
DH Peg. A conclusion is made about the existence of the shock wave in
the atmosphere of this star. The anomalous shortwave displacement of
Hα line in the light minimum is noted.
