It is shown that strange quark matter ( SQM ) objects , stars and planets , can very efficiently convert the mechanical energy into hadronic energy when they oscillate .
This is because the mass density at the edge of SQM objects , \rho _ { 0 } { = } 4.7 { \times } 10 ^ { 14 } \frac { { \mathrm { g } } } { { \mathrm { cm } ^ { 3 } } } , is the critical density below which strange quark matter is unstable with respect to decay into photons , leptons .
We consider here radial oscillations of SQM objects that could be induced in stellar or planetary systems where tidal interactions are ubiquitous .
Already oscillations of 0.1 \% radius amplitude result in 1 \mathrm { keV } per unit baryon number excitation near the surface of SQM stars .
The excitation energy is converted into electromagnetic energy in a short time of 1 \mathrm { m { } sec } , during a few oscillations .
Higher amplitude oscillations result in faster energy release that could lead to fragmentation or dissolution of SQM stars .
This would have significant consequences for hypothetical SQM star binaries and planetary systems of SQM planets with regard to gravitational wave emission .
