Precession of triaxially deformed neutron stars

Understand

A deformed neutron star (NS) will precess if the instantaneous spin axis and the angular momentum are not aligned.

• Such a precession can produce continuous gravitational waves (GWs) and modulate electromagnetic pulse signals of pulsars.
• In this contribution we extend our previous work in a more convenient parameterization.
• We treat NSs as rigid triaxial bodies and give analytical solutions for angular velocities and Euler angles.
