Rotation and deformation of strangeon stars in the Lennard Jones model
Gao, Yong
We use Hartle and Thorne's formalism to study the moment of inertia and rotational deformation of strangeon stars. Tidal deformabilities of strangeon stars are also performed via general relativistic perturbation theory. We find that the moment of inertia (I), the tidal love numbers (\Lambda), and the mass quadrupole (Q) satisfy the I-Love-Q universal relation. The frame dragging effect in the timing signal of double pulsars and tidal measurements in gravitational waves from binary pulsar-like compact stars can give constraints on the equation of state of strangeon stars.
