Projectors and polarization states
The projectors
and the polarization states using the N, p, q triad
Compact binaries and the post-Newtonian (PN) approximation
Small velocity (neglect ultra-relativistic effects)
Small gravitational potential (neglect extreme gravitational effects)
Spin is treated as a PN perturbation
Newtonian or quadrupole term
Higher order PN corrections
Spin-Orbit corrections
The transverse-traceless tenzor in the PN approximation
Research plan• Description of the motion and
the method in the Lense-Thirring picture
• Description of the motion and the method in the finite mass case
• Description of the motion and the method in the general case
• Explicit time dependence – numerical integration
• Polarization states in the Lense-Thirring picture, effects of eccentricity and spin
• Polarization states in the finite mass case, effects of eccentricity and spin, extreme mass ratio limit
• Polarization states in the general case, effects of eccentricity and spins, extreme mass ratio limit, one spin limit, lowest order spin-spin contributions
• Innermost Stable Circular Orbit case
