Using NASA’s Kepler space telescope, Chinese astronomers have observed a binary star system known as KIC 5623923. As a result, they found that the investigated system is a faint eclipsing binary experiencing Delta Scuti-type pulsations. The new findings were published Nov. 24 on the arXiv pre-print server.

Delta Scuti stars are pulsating variables with spectral types between A and F, named after the Delta Scuti variable in the constellation Scutum. They exhibit radial and non-radial pulsations spanning periods from 20 minutes to eight hours. Studying pulsation behavior of Delta Scuti variables could help us advance our knowledge about stellar interiors.
