The eclipsing binary star RZ Cas: accretion-driven variability of the multimode oscillation spectrum 2018 We analysed photometric time series of the active, semi-detached Algol-type system RZ Cas obtained in 1999-2009, in order to search for seasonal and short-term variations in the oscillation spectrum of RZ Cas A. The orbital period shows ±1 s cyclic variations on time-scales of 6-9 years. We detected six low-degree p-mode oscillations with periods between 22.3 and 26.22 min and obtained safe mode identifications using the periodic spatial filter method. The amplitudes and frequencies of all modes vary. NO binaries: eclipsing stars: oscillations Lehmann, H. Rodríguez, E. Olson, E. Kim, S.-L. Kusakin, A. V. Lee, J. W. Youn, J.-H. Kwon, S.-G.
