Chinese astronomers observe Delta Scuti pulsations in faint eclipsing binary KIC 5623923

Chinese astronomers using NASA's Kepler telescope have identified KIC 5623923 as a faint eclipsing binary exhibiting Delta Scuti-type pulsations. The system's pulsations, previously thought to originate from the secondary star, are now believed to come from the primary star, which is within the classical pulsating instability strip. The study, published on arXiv, also determined the system's orbital period to be 1.21 days and measured the effective temperatures and luminosities of both stars.
