TIME-SERIES SPECTROSCOPY OF THE PULSATING ECLIPSING BINARY XX CEPHEI
TIME-SERIES SPECTROSCOPY OF THE PULSATING ECLIPSING BINARY XX CEPHEI
Oscillating Algol-type eclipsing binaries (oEA) are very interesting objects that have three observational features of eclipse, pulsation, and mass transfer. Direct measurement of their masses and radii from the double-lined radial velocity data and photometric light curves would be the most essential for understanding their evolutionary process and for performing …
