SEARCH OF VARIABILITY OF THE COMPANION OF THE CLASSICAL CEPHEID EV SCT

I. A. Egorova, V. V. Kovtyukh

Анотація


Spectroscopic observations of EV Sct obtained on 4m telescope at KPNO showed that the secondary component is probably situated within the instability strip (Kovtyukh & Andrievsky, 1999). Some observers (Pel, 1976; Mermilliod, 1987) have noted a signicant data scattering on the light curve. Therefore the companion of EV Sct perhaps is a small amplitude variable star. We present results of photoelectric observations of the EV Sct.
