The system V389 Cas: Algol-type binary with δδ-Scuti pulsations

• V389 Cas is detached eclipsing binary on circular orbit.
• Delta Scuti pulsations were found on secondary component.
• These pulsations have the period of about 0.037 day.

New CCD observations of V389 Cas were carried out in the observatories in the Czech Republic from 2010 to 2014. These new data were analysed using the program PHOEBE. V389 Cas was found to be a detached eclipsing binary system with two rather different components moving on a circular orbit. Moreover, there was discovered also a δδ-Scuti-type behaviour of the secondary component. These pulsations have the period of about 0.037 day. This result is being compared with the previous findings on similar eclipsing-pulsation systems published by Zhang et al. (2013).
