Abstract
We investigate the dynamical behavior of strange quark matter (SQM) objects, such as stars and
planets, when subjected to radial oscillations induced by tidal interactions in stellar systems. Our
study demonstrates that SQM objects can efficiently convert mechanical energy into hadronic
energy due to the critical mass density at their surfaces of 4.7×1014 gcm−3, below which SQM
becomes unstable and decays into photons, hadrons, and leptons. We show that even small
amplitude radial oscillations, with a radius change of as little as 0.1%, can result in significant
excitation energies near the surface of SQM stars. This excitation energy is rapidly converted
into electromagnetic energy over short timescales (approximately 1ms), potentially leading to
observable astrophysical phenomena. Higher amplitude oscillations may cause fragmentation or
dissolution of SQM stars, which has important implications for the evolution of binary systems
containing SQM objects and the emission of gravitational waves.
