A planet has been discovered with a composition believed to be made up of diamond. If such a planet were to host a massive satellite of high eccentricity, it seems possible that the large tidal forces induced by the moon on the planet could give rise to a piezoelectric phenomenon in the planet's crystalline structure. This could potentially generate a large magnetic field around the planet in the direction orthogonal to the orientation of the satellite's perihelion, which could, in turn, induce electromagnetic oscillations. The planet would essentially become a crystal oscillator, pulsing an electromagnetic field. Crystalline structures also have large tensile strength. Therefore, it seems possible that such a planet could survive these intense tidal forces and the resulting oscillation deformations. Are there any physical problems with such a theoretical scenario?

Note: Further research has called into question the possible origin of the discovered planet's diamond composition. Nevertheless, the researchers suggest that, depending on where the planet formed in its system's protoplanetary disk, a diamond composition could be possible.

    $\begingroup$ This is speculation piled upon speculation. Is there a reference for a planet claimed to be made of crystalline carbon? $\endgroup$ – Rob Jeffries Oct 7 '17 at 11:31
  • $\begingroup$ Yes, I have added the reference to the post. $\endgroup$ – Master Drifter Oct 7 '17 at 12:08
  • $\begingroup$ Fair enough. But a more likely example would be a white dwarf with a planet, since most have cooled and crystallised. $\endgroup$ – Rob Jeffries Oct 7 '17 at 12:16
